Taking over the Atlas
Dear Colleagues,
The Atlas, once more, is in great danger, and I will have to proceed to a collective economic lay-off of all the team involved in the Atlas before the begining of April 2015 (a foundation having suddenly withdrawn its commitment to support the Atlas). I ask you herein if any Scientific Society (a Society of Cytogenetics, of Clinical Genetics, of Hematology, or a Cancer Society, or any other...), any University and/or Hospital, any Charity, or any database would be interested in taking over the Atlas, in whole or in part. If taking charge of the whole lot is too big, a consortium of various actors could be the solution (I am myself trying to find partners). Could you please spread the information, contact the relevant authorities, and find partners.
Survival of the Atlas will be critically dependant upon your ability to find solutions (and urgently!).
Kind regards.
Jean-Loup Huret
Donations are also welcome
If each casual visitor gives 3 Euros or Dollars, the Atlas is saved in a week !
If each professional gives 100 Euros or Dollars once a year (now), the Atlas is saved in 2 weeks !
Don't let the Atlas imminent demise
Note: we send fiscal receipts for donations equal or above 50 Euros or Dollars

SRSF3 (serine/arginine-rich splicing factor 3)


Other namesSFRS3
LocusID (NCBI) 6428
Location 6p21.31
Location_base_pair Starts at 36562090 and ends at 36572244 bp from pter ( according to hg19-Feb_2009)


  Diagram of genomic structure of SRSF3 gene. The numbers above the diagram are the nucleotide positions in SRSF3 gene. The open boxes and broken lines represent exons and introns, respectively.
Description SRSF3 gene contains 6 exons and spans 10155 bp on the plus (+) strand of the short arm of chromosome 6.
Transcription SRSF3 mRNA is in size of 3144 nts and encodes a protein with 164 amino acid residues. By including an alternative exon between exon 3 and exon 4, SRSF3 pre-mRNA could generate additional isoform of SRSF3 transcript.
Pseudogene No.


  Diagram of protein structure of SRSF3. The numbers below the diagram are the amino acid positions in SRSF3 protein. SRSF3 has an RNA recognition motifs (RRM) in the N-terminus and an arginine/serine-rich domain (RS) at the C-terminus. RRM motif identifies and binds specific RNA sequences. RS domain interacts with other proteins and facilitates recruitment of the spliceosomal components. The serine residues of the RS domain can be phosphorylated.
Description 164 amino acid residues, 20 kDa.
Expression Expression of SRSF3 varies significantly in different cell types. For example, the expression of SRSF3 is abundant in the undifferentiated or intermediately differentiated keratinocytes in the basal and parabasal layers, but drops significantly in terminally differentiated keratinocytes in the superficial layers of the cervix or skin. In general, normal cells like muscle or nerve cells have no or little expression of SRSF3. In contrast, malignant tumor cells express remarkable amount of SRSF3 when compared to their normal counterparts.
Localisation SRSF3 is a shuttling protein between nucleus and cytoplasm.
Function SRSF3 is a splicing factor and involved in the regulation of RNA splicing. It affects alternative splicing by interacting with RNA cis-elements in a concentration and cell differentiation-dependent manner. Moreover, SRSF3 plays important roles in RNA export from nuclear to cytoplasm, termination of transcription, alternative RNA polyadenylation, and protein translation. SRSF3 is required for embryonic development and cell cycle progression. SRSF3 at increased expression is tumorigenic and is required for tumor initiation, progression, and maintenance.

Alternative splicing of pre-mRNA
SRSF3 controls viral early to late switch by regulation of gene expression of bovine papillomavirus type 1 and human papillomavirus through interaction with A/C-rich RNA elements (Jia et al., 2009). SRSF3 promotes the inclusion of exon 4 of its own mRNA and reduces the expression of full length SRSF3 protein (Juma and Nielsen, 1997). SRSF3 activates the inclusion of exon 10 of PK-M gene to promote the expression of oncogenic M2 isoform (Wang et al., 2012). SRSF3 inhibits the inclusion of a fibronectin cassette exon in the mature mRNA by interacting with RNA polymerase II C-terminal domain (de la Mata and Kornblihtt, 2006).

Termination of transcription
SRSF3 plays a role in termination of transcription by binding to RNA downstream of the cleavage site, facilitating its degradation, and the release of Pol II from template DNA (Cui et al., 2008).

Alternative polyadenylation
The 3'-terminal exon 4 of calcitonin pre-mRNA contains an alternative polyadenylation site. SRSF3 affects the inclusion of exon 4 and alternative polyadenylation by the interaction with CstF (Lou et al., 1998).

RNA export
SRSF3 associates with TAP promoting the export of intronless mRNA of histone H2a gene by interacting with a 22-nt RNA element (Huang et al., 2003; Huang and Steitz, 2001).

Protein translation
SRSF3 is required for poliovirus translation initiation. SRSF3 binds to internal ribosome entry site (IRES) of a viral RNA by interaction with PCBP2 (Bedard et al., 2007).

Homology Human SRSF3 protein is highly conserved in chimpanzee, dog, sheep, cow, mouse, rat, chicken, zebrafish and so on. SRSF3 is the smallest member of SR (serine/arginine-rich) family and shares a high homology with other members. All of SR proteins contain at least one RRM and one downstream RS domain enriched in repeating arginine-serine dipeptides.


Note There is one mutation which causes amino acid residue change according to NCBI dbSNP database.

Implicated in

Entity Cancer
Note SRSF3 is a protooncogene. Overexpression of SRSF3 has been found in various cancers, including cervix, lung, breast, stomach, skin, bladder, colon, liver, thyroid, and kidney; and in various soft tissue tumors, including B-cell lymphoma, rhabdomyosarcoma, hemangioendothelioma, hemangiopericytoma, neurofibroma, neurilemmoma, liposarcoma, leiomyosarcoma, histiocytoma, and synovial sarcoma. SRSF3 at overexpression has transformation activity for MEF/3T3 cells, a mouse embroynic fibroblast cell line. SRSF3 controls cell cycle progression and thereby cell proliferation presumably by regulating the expression of forkhead box transcription factor M1 (FoxM1), PLK1 and Cdc25B.
