About SRSF3

Cytogenetic location: 6p21.31-p21.2 Genomic coordinates (GRCh38): 6:36,594,362-36,605,600 (from NCBI)

This gene has 8 transcripts (splice variants), 319 orthologues, 8 paralogues and is associated with 50 phenotypes. Ubiquitous expression in bone marrow (RPKM 107.3), lymph node (RPKM 60.0) and 25 other tissues.

Summary

The protein encoded by this gene is a member of the serine/arginine (SR)-rich family of pre-mRNA splicing factors, which constitute part of the spliceosome. Each of these factors contains an RNA recognition motif (RRM) for binding RNA and an RS domain for binding Other proteins. The RS domain is rich in serine and arginine residues and facilitates interaction between different SR splicing factors. In addition to being critical for mRNA splicing, the SR proteins have also been shown to be involved in mRNA export from the nucleus and in translation. Two transcript variants, one protein-coding and the Other non-coding, have been found for this gene. [provided by RefSeq, Sep 2010]
