Pcsk4 Gene Summary [Rat]
Predicted to enable serine-type endopeptidase activity. Predicted to be involved in several processes, including binding activity of sperm to zona pellucida; peptide hormone processing; and sperm capacitation. Predicted to be located in acrosomal membrane. Predicted to be active in Golgi membrane and trans-Golgi network. Human ortholog(s) of this gene implicated in colorectal adenocarcinoma. Orthologous to human PCSK4 (proprotein convertase subtilisin/kexin type 4). [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 Pcsk4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
