|Synonyms||FUSIP1, FUSIP2, SFRS13A, TASR|
|Function||Splicing factor that in its dephosphorylated form acts as a general repressor of pre-mRNA splicing. Seems to interfere with the U1 snRNP 5'-splice recognition of SNRNP70. Required for splicing repression in M-phase cells and after heat shock. May be involved in regulation of alternative splicing in neurons, with isoform 1 acting as a positive and isoform 3 as a negative regulator.|
|Cellular Location||Nucleus speckle. Cytoplasm|
|Tissue Location||Widely expressed.|

This gene product is a member of the serine-arginine (SR)family of proteins, which is involved in constitutive and regulatedRNA splicing. Members of this family are characterized byN-terminal RNP1 and RNP2 motifs, which are required for binding toRNA, and multiple C-terminal SR/RS repeats, which are important inmediating association with other cellular proteins. This proteincan influence splice site selection of adenovirus E1A pre-mRNA. Itinteracts with the oncoprotein TLS, and abrogates the influence ofTLS on E1A pre-mRNA splicing. This gene has multiple pseudogenes.Alternative splicing of this gene results in multiple transcriptvariants encoding different isoforms. In addition, transcriptvariants utilizing alternative polyA sites exist.
