Target data

Function

Necessary for the splicing of pre-mRNA. It is required for formation of the earliest ATP-dependent splicing complex and interacts with spliceosomal components bound to both the 5'- and 3'-splice sites during spliceosome assembly. It also is required for ATP-dependent interactions of both U1 and U2 snRNPs with pre-mRNA. Interacts with other spliceosomal components, via the RS domains, to form a bridge between the 5'- and 3'-splice site binding components, U1 snRNP and U2AF. Binds to purine-rich RNA sequences, either 5'-AGSAGAGTA-3' (S=C or G) or 5'-GTTCGAGTA-3'. Can bind to beta-globin mRNA and commit it to the splicing pathway. The phosphorylated form (by SRPK2) is required for cellular apoptosis in response to cisplatin treatment.

Specificity

This antibody recognizes a phospho-epitope of the non-snRNP (small nuclear ribonucleoprotein particles) factor SC35. The antibody reacts with the splicing factor SC-35 and with the SC-35-related non-snRNP factor SF2/ASF. Recent data suggests this clone may cross-react with additional proteins within the spliceosome complex (PMID: 33095160)

Activity summary

SC35 also known as SRSF2 (serine/arginine-rich splicing factor 2) is an essential splicing factor with a molecular mass around 26 kDa. This protein is part of the SR protein family which are known for their roles in splicing regulation due to their serine/arginine-rich domains. SC35 predominantly localizes in the nucleus of cells where it accumulates in nuclear speckles areas rich in splicing factors. Biologists often use immunofluorescence techniques and anti-SC antibodies to visualize and study SC35's localization and function within cells.

Biological function summary

SC35 influences various aspects of mRNA processing particularly pre-mRNA splicing. The protein functions as a splicing enhancer by interacting with pre-mRNA at specific sites to assist exon inclusion during splicing. SC35 acts as part of the spliceosomal complex which is critical during the assembly and rearrangement of the spliceosome. Additionally it interacts with other splicing factors to ensure accurate and efficient splicing which is fundamental for gene expression and consequent protein synthesis.

Pathways

The SC35 protein participates in the RNA splicing pathway a significant process in mRNA maturation and gene expression regulation. This protein interacts with other SR proteins like SRSF1 and components of the spliceosomal machinery. SC35's function is also important in the alternative splicing pathway impacting the diversity of mRNA transcripts through the production of different exon combinations. By regulating alternative splicing SC35 helps produce protein diversity vital for numerous cellular processes.

Associated diseases and disorders

Changes in SC35 expression or function have been linked to several human conditions. Notably its dysregulation can contribute to cancer development through altered splicing patterns that impact oncogene and tumor suppressor gene expression. Furthermore SC35 abnormalities are associated with spinal muscular atrophy a neurodegenerative disorder where splicing regulation plays a significant role. In these diseases SC35 may interact with other proteins such as SMN (survival of motor neuron protein) and impact their functions highlighting its relevance in maintaining cellular health.
