DNA/RNA

Description The GAB2 gene is composed of 10 exons spanning a region of 222666 bp (see Mapping for details).
Pseudogene Not known.

Protein

Note PubMed predicts two distinct subtypes encoded by alternative transcripts. The variant GRB2-associated binding protein 2 isoform b contains an alternate exon 1 compared to transcript variant 1. It maintains the same reading frame, but encodes the shorter isoform (b), which lacks aa 1-38 of isoform a (for details see AA865573, AB011143).
Description Amino acids: 766. Calculated molecular mass: 74,327 kDa. However, presumably due to its richness in proline residues and its high degree of phosphorylation, GAB2 usually runs around 95 kDa in conventional SDS-PAGE gels. GAB2 protein isolated from cells stimulated via growth factors, cytokines or antigen receptors exhibit a prominent electrophoretic mobility shift, which reflects the high degree of feedback phosphorylation events at Ser/thr-residues.
This protein is a member of the GRB2-associated binding protein (GAB)/daughter-of-sevenless (DOS) family and is similar to the well studied GAB1 protein. These docking proteins contain pleckstrin homology (PH) domain, and are recruited to various receptors via small adaptor proteins such as the GRB2 adapter protein.
Expression At low levels, GAB2 is presumably expressed in a wide range of tissues and cell types. Prominent expression is observed in various hematopoietic and neuronal lineages. Aberrant overexpression has been observed in various malignancies such as breast cancer, melanoma, acute myeloid leukemia, ovarian and gastric carcinoma.
Localisation Mainly cytoplasmic in unstimulated cells, however this protein is recruited to the plasmamembrane by various stimuli. This recruitment process requires either the PH domain and/or the small adaptor protein GRB2, either alone or in conjunction with adaptor proteins of the SHC family.
Function Gab/DOS proteins integrate and amplify signals from growth factor, cytokine and antigen receptors as well as from cell adhesion molecules. They also diversify signals by channelling the input information from activated receptors into signalling pathways with distinct biological functions. Gab proteins are subject to a complex regulation by feed-forward and feedback phosphorylation events as well as protein-protein interactions. Gab/DOS docking proteins organise entire signalling subsystems and thereby fulfil an important if not essential role in many physiological processes. GAB2 is implicated in various differentiation processes within the hematopoietic and nervous systems. In particular, GAB2 deficient mice display impaired osteoclast development and consequently display osteopetrosis. GAB2 is also essential for the FceRI-mediated degranulation of murine mast cells.
Aberrant expression and/or signalling by GAB2 has been increasingly linked to human diseases from various forms of neoplasia over inflammation to Alzheimer's disease.
A detailed recent review on GAB2 can be found in Wohrle et al. (2009a).
Homology The closest relative is the putative product of the GAB4 gene, followed by the well studied GAB1 and less studied GAB3 protein. Gab-like proteins have been also identified in Drosophila melanogaster (daughter-of-seveless (DOS)) and Caenorhabditis elegans (Suppressor-of-clear 1 (SOC1)).

Implicated in

Note
  
Entity Breast cancer
Note GAB2 is frequently over-expressed in human breast cancer cell lines and primary tumours. Overexpression of GAB2 has been shown to be an early event in breast cancer development. In response to EGF, insulin and bFGF stimulation, GAB2 becomes tyrosine phosphorylated indicating that these RTKs, which are implicated in breast cancer development or progression, use this docking protein to amplify their signals. There might be several, not necessarily mutually exclusive mechanisms by which GAB2 is up-regulated in breast cancer such as the amplification of the GAB2 locus, which resides in a region commonly amplified in breast cancers or the aberrant activity of the E2F transcription factor, which is often dysregulated in tumours and binds directly to the human GAB2 promoter. Furthermore, the expression of both GAB2 mRNA and protein is induced by estradiol in an estrogen receptor-dependent manner. Modelling GAB2 expression levels to those observed in breast cancer in the immortalised, but non-transformed, human mammary epithelial cell MCF-10A implies that overexpression of this docking protein contributes to various aspects of malignant transformation such as increased proliferation and reduced growth factor requirements.
Studies from various laboratories using the MCF-10A model system as well as transgenic mouse models suggest that GAB2 also cooperates with other oncogenes implicated in breast cancer development such as HER2 and SRC. Indeed, a recent study by Bocanegra et al. (2009) has shown that small interfering RNA (siRNA)-mediated knockdown of GAB2 in breast cancer lines with GAB2 amplification revealed a dependency on GAB2 for cell proliferation, cell-cycle progression, survival and invasion, likely mediated through altered phosphatidylinositol 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) signaling. These findings are in agreement with studies in MCF-10A cells in which ectopically expressed GAB2 affects these biological parameters via the same effector pathways. GAB2 knockdown also impaired the proliferation and survival in the BT474 cell line, which contains a ERBB2 amplification, consistent with previous studies implicating GAB2 as an important downstream effector of this receptor tyrosine kinase.
  
  
Entity Melanoma
Note Two recent studies implicate GAB2 in malignant melanoma. Firstly, Horst et al. (2009) have shown that the GAB2 gene is amplified and/or over-expressed in 11% and 50% of human metastatic melanomas, respectively. Moreover, Chernoff et al. (2009) demonstrated that GAB2 amplification is associated with melanoma arising from sun-protected sites and often occurs independently from oncogenic NRAS or BRAF mutations or amplification of the KIT gene. Importantly, knockdown and over-expression experiments revealed that GAB2 enhances the migratory and invasive behaviour of melanoma cells. In contrast to metastatic melanoma, normal human melanocyte lines, melanocytic nevi and primary melanomas displayed low GAB2 expression levels suggesting that GAB2 overexpression might represent a marker of neoplastic progression.
  
  
Entity Myeloid leukemias
Note The first evidence for a critical contribution of GAB2 to leukemogenesis was the observation that myeloid progenitors from GAB2-deficient mice are resistant to transformation by the BCR-ABL oncoprotein, which arises from a chromosomal translocation found in more than 90% of patients with chronic myeloid leukaemia (CML). Phosphorylation of Y177 within the BCR moiety leads to recruitment of the GRB2/GAB2 complex and downstream signalling via SHP2 and PI3K, two crucial events for enhanced proliferation and survival. Similarly, the oncogenic BCR-FGFR1 fusion protein, which consists of a BCR-derived moiety and the tyrosine kinase domain of the fibroblast growth factor receptor 1 (FGFR1), drives the tyrosine phosphorylation of GAB2 in murine bone marrow cells and their malignant transformation through phospho-Y177 mediated GRB2 association.
These findings suggest that GRB2-mediated recruitment of GAB2 to oncogenic fusion protein tyrosine kinases is a critical event for the induction of a CML-like disease.
The contribution of GAB2 to BCR-ABL signaling is further supported by the observation that shRNA-mediated silencing of endogenous GAB2 inhibits proliferation and colony formation of CD34+ cells from CML patients.
GAB2 is also involved in the pathogenesis of several other leukemias. The oncogenic fusion kinases TEL-ABL and TEL-JAK2 engage GAB2 in a similar manner as BCR-ABL.
The gene encoding the GAB2 interaction partner SHP2, represents the most common target of somatic mutations in juvenile myelomonocytic leukemia (JMML), a rare, albeit aggressive myelo-proliferative disorder occurring in children. The most frequently JMML-associated mutation, E76K, confers enhanced catalytic activity to SHP2 and requires GAB2 for transformation of primary murine myeloid progenitors.
  
  
Entity Other neoplasia
Note Amplification and/or over-expression of the human GAB2 gene has been also recently reported for ovarian and gastric carcinoma as well as for acute myeloid leukemia (AML). However, additional functional studies are needed to dissect the role that GAB2 plays in these malignancies.
