Description LASP1 encompasses 51.65 kb on the genomic level and consists of 7 exons
Transcription 3845 bp mRNA, 783 bp coding sequence


Description 261 amino acids; 29 kDa. LASP1 encodes a member of a LIM (Lin-11, Isl-1 and Mec-3) protein subfamily and is characterized by a LIM motif (cysteine-rich LIM/double zinc finger motif) at the N-terminus, an SH3 domain (Src homology region 3) at the C-terminus, and two actin-binding domains in the core of the protein
Expression ubiquitous
Localisation intracellular, cytoplasmic; associated with the F-actin rich cortical cytoskeleton
Function LASP1 plays an important role in the regulation of dynamic actin-based, cytoskeletal activities and cell motility. Agonist-dependent changes in LASP1 phosphorylation may also serve to regulate actin-associated ion transport activities, not only in the parietal cell but also in certain other F-actin-rich secretory epithelial cell types. Together, (LIM-) nebulette, Lasp-1, and zyxin may play an important role in the organization of focal adhesions.
Homology LASP family of proteins: actin-binding repeats similar to those in LASP1 are also present in other nebulin-related proteins such as NEBL (nebulette, 107 kD actin-binding Z-disk protein) and NRAP (nebulin-related anchoring protein); NRAP also contains an N-terminal LIM domain and NEB (nebulin) a C-terminal SH3 domain, both of which are highly homologous to the respective domains of LASP1.

Implicated in

Entity t(11;17)(q23;q12) --> MLL-LASP1
Disease infant AML-M4; only one case described so far
Abnormal Protein the MLL-LASP1 chimeric protein consists of the AT-hook DNA-binding domain and the methyltransferase motif including the CXXC zinc-finger domain of MLL and the SH3 domain of LASP1
Entity breast carcinomas
Disease 17q11-q21 amplification is found in about 25% of primary breast carcinomas; simultaneous amplification and overexpression of LASP1 and ERBB2
Prognosis poor clinical outcome; increase risk of relapse
