Msr1 Gene Summary [Rat]
Predicted to enable amyloid-beta binding activity; cargo receptor activity; and low-density lipoprotein particle binding activity. Predicted to be involved in several processes, including endocytosis; positive regulation of cholesterol storage; and positive regulation of macrophage derived foam cell differentiation. Predicted to act upstream of or within establishment of localization in cell and lipoprotein transport. Predicted to be located in plasma membrane. Human ortholog(s) of this gene implicated in Barrett's esophagus; arteriosclerosis; and prostate cancer. Orthologous to human MSR1 (macrophage scavenger receptor 1).

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 Msr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
