Masp1 Gene Summary [Mouse]
Enables serine-type endopeptidase activity. Involved in complement activation, lectin pathway. Located in extracellular space. Is expressed in several structures, including alimentary system; brain; genitourinary system; liver; and spleen. Human ortholog(s) of this gene implicated in 3MC syndrome 1. Orthologous to human MASP1 (MBL associated serine protease 1). [provided by Alliance of Genome Resources, Apr 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 mouse Masp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
