Psip1 Gene Summary [Rat]
Enables supercoiled DNA binding activity. Predicted to be involved in several processes, including mRNA 5'-splice site recognition; positive regulation of transcription by RNA polymerase II; and response to heat. Located in euchromatin and heterochromatin. Orthologous to human PSIP1 (PC4 and SRSF1 interacting protein 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Psip1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
