LMAN1 Antibody / ERGIC-53

Protein ERGIC-53, also known as ER-Golgi intermediate compartment 53 kDa protein or lectin mannose-binding 1, is a protein that in humans is encoded by the LMAN1 gene. It is mapped to 18q21.32. The protein encoded by this gene is a membrane mannose-specific lectin that cycles between the endoplasmic reticulum, endoplasmic reticulum-Golgi intermediate compartment, and cis-Golgi, functioning as a cargo receptor for glycoprotein transport. The protein has an N-terminal signal sequence, a calcium-dependent and pH-sensitive carbohydrate recognition domain, a stalk region that functions in oligomerization, a transmembrane domain, and a short cytoplasmic domain required for organelle targeting. Allelic variants of this gene are associated with the autosomal recessive disorder combined factor V-factor VIII deficiency.
