Target Information
Serine/arginine-rich protein 75 (SRp75) is encoded by the SRSF4 gene. SRp75 belongs to the arginine/serine-rich factor family and likely plays a role in alternative mRNA splicing.
SR factors contain one or more RNA recognition motifs (RRM) and an arginine/serine (RS)-rich domain. They are essential for constitutive splicing and regulate splicing in a concentration-dependent manner by influencing alternative splice site selection.
Most SR proteins, including SC35 and SRp40, are confined to the nucleus, while SF2/ASF, SRp20, and 9G8 shuttle between the nucleus and cytoplasm, contributing to mRNA transport.
The activity of SR proteins in regulated splicing is antagonized by hnRNP A/B family members, which induce shifts in splice site selection.
