Gpat4 Gene Summary [Mouse]
Enables glycerol-3-phosphate O-acyltransferase activity. Involved in lactation and triglyceride biosynthetic process. Acts upstream of or within several processes, including acylglycerol metabolic process; glandular epithelial cell maturation; and mammary gland development. Located in endoplasmic reticulum. Is expressed in several structures, including adipose tissue; genitourinary system; liver; mammary gland; and spleen. Orthologous to human GPAT4 (glycerol-3-phosphate acyltransferase 4).

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 mouse Gpat4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
