Meprin A subunit alpha also known as endopeptidase-2 or PABA peptide hydrolase is the alpha subunit of the meprin A enzyme that in humans is encoded by the MEP1A gene. [5] [6] The MEP1A locus is on chromosome 6p in humans and on chromosome 17 in mice. [7]
The meprin alpha subunit product of the MEP1A gene is processed in the endoplasmic reticulum during intracellular transport, and is secreted as homomeric meprin A. Meprin alpha subunits may self-associate, and once secreted, form very large multimers, with a molecular mass of over 1 million daltons. In cells concurrently expressing MEP1B, the meprin alpha and meprin beta subunits form disulfide dimers that interact to form membrane bound heterotetrameric meprin A.
Serine/threonine-protein phosphatase PP1-beta catalytic subunit is an enzyme that in humans is encoded by the PPP1CB gene.
Inhibin, alpha, also known as INHA, is a protein which in humans is encoded by the INHA gene.
Integrin beta-5 is a protein that in humans is encoded by the ITGB5 gene.
Liver carboxylesterase 1 also known as carboxylesterase 1 is an enzyme that in humans is encoded by the CES1 gene. The protein is also historically known as serine esterase 1 (SES1), monocyte esterase and cholesterol ester hydrolase (CEH). Three transcript variants encoding three different isoforms have been found for this gene. The various protein products from isoform a, b and c range in size from 568, 567 and 566 amino acids long, respectively.

Neuronal acetylcholine receptor subunit alpha-5, also known as nAChRα5, is a protein that in humans is encoded by the CHRNA5 gene. The protein encoded by this gene is a subunit of certain nicotinic acetylcholine receptors (nAchR).
Disintegrin and metalloproteinase domain-containing protein 28 is an enzyme that in humans is encoded by the ADAM28 gene.
Guanine nucleotide-binding protein subunit alpha-11 is a protein that in humans is encoded by the GNA11 gene. Together with GNAQ, it functions as a Gq alpha subunit.
MAM domain is an evolutionary conserved protein domain. It is an extracellular domain found in many receptors.
Meprin A is an enzyme that cleaves protein and peptide substrates preferentially on carboxyl side of hydrophobic residues. This metalloprotease can be associated with inflammatory responses. It can be found in the extracellular space where it can also form complex structures by joining its monomers together.
Astacins are a family of multidomain metalloendopeptidases which are either secreted or membrane-anchored. These metallopeptidases belong to the MEROPS peptidase family M12, subfamily M12A. The protein fold of the peptidase domain for members of this family resembles that of thermolysin, the type example for clan MA and the predicted active site residues for members of this family and thermolysin occur in the motif HEXXH.
Meprin B is an enzyme. This enzyme catalyses the following chemical reaction
