The SF3A3 antibody targets the SF3A3 protein, a key component of the SF3a complex within the U2 small nuclear ribonucleoprotein (snRNP) of the spliceosome. The spliceosome mediates pre-mRNA splicing by recognizing intron-exon boundaries and catalyzing intron removal. SF3A3. along with SF3A1 and SF3A2. forms the SF3a subcomplex critical for stabilizing U2 snRNP binding to the branch site during spliceosome assembly.
Antibodies against SF3A3 are widely used in research to study spliceosome dynamics, RNA splicing mechanisms, and their dysregulation in diseases. Aberrant splicing linked to SF3A3 mutations or altered expression is implicated in cancers, neurological disorders, and developmental defects. For example, SF3A3 overexpression has been observed in certain tumors, correlating with abnormal splicing events that promote oncogenesis.
These antibodies enable techniques like Western blotting, immunofluorescence, and immunoprecipitation to analyze SF3A3 expression, localization, and interactions. They also support drug discovery efforts targeting spliceosome components, as SF3A3 inhibitors are explored for anticancer therapies. Notably, SF3A3 antibodies help validate the efficacy of small molecules like pladienolide derivatives that disrupt spliceosome activity.
Overall, SF3A3 antibodies serve as essential tools for elucidating splicing biology and developing therapeutic strategies for splicing-related pathologies. (Word count: 199)
