| Description |
Y116A8C.32 encodes an ortholog of splicing factor SF1, which enables 3' splice site recognition by binding U2AF65 and the intron branch site during splicing complex formation; Y116A8C.32 shares several domains with mammalian SF1 proteins (a U2AF65 binding domain, a hnRNP K homology domain, two RNA-binding zinc knuckles, and a proline-rich C-terminal domain), while also sharing a hydrophilic N-terminal domain (enriched for serine, arginine, lysine, and aspartate) with Drosophila but not mammalian SF1; Y116A8C.32's N-terminal domain resembles RS domains in other splicing proteins; Y116A8C.32 is required for embryonic viability, normally rapid growth, and proper body morphology. |
