SUBCELLULAR LOCALIZATION

plasma membrane

basic FUNCTION	carboxypeptidase M cleaving basic C terminal amino acids in monocyte to macrophage differentiation
	membrane-bound zinc-dependent protease that cleaves C-terminal basic residues, such as arginine or lysine, from peptides/proteins 1)
	likely a cellular player in lipid uptake and/or metabolism of activated macrophages (MAs) by promoting foam cell formation
	could likely promote foam cell formation by acting in the lipid regulation process of macrophages
	inhibition of CPM, the key enzyme involved in the biosynthesis of BDKRB1 agonists, could exert the same beneficial effects to BDKRB1 antagonism in insulin resistance
	is a glycosylphosphatidylinositol anchored enzyme that plays an important role in the kallikrein-kinin system (KKS)

CELLULAR PROCESS	cell life, differentiation

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA

RNA

small molecule	metal binding,
	zinc Zn2+

protein	activating peptide hormones at local tissue sites, before or after binding to their ligands
	close relationship of BDKRB1 and CPM on the membrane is required for efficiently generatingoles in inflammation
	spatial proximity between ACE and the endogenous CPM BDKRB1 signals, which play important r enables an ACE-evoked release of CPM
	BDKRB1 positively modulates both CPM expression and activity, suggesting that CPM-BDKRB1 interaction in membrane microdomains might affect enzyme activity, beyond interfering in receptors signaling

Variant & Polymorphism other	rs12812500 variant of the CPM gene may increase silicosis susceptibility

Candidate gene
Marker	CPM is a novel marker in lipid uptake and/or metabolism of activated macrophages (MAs) by promoting foam cell formation
	identification of CPM amplification could be used as an alternative diagnostic tool for the diagnosis of well-differentiated liposarcoma/atypical lipomatous tumors
