The protein encoded by this gene is a type II transmembrane glycoprotein and a common acute lymphocytic leukemia antigen that is an important cell surface marker in the diagnosis of human acute lymphocytic leukemia (ALL). The encoded protein is present on leukemic cells of pre-B phenotype, which represent 85% of cases of ALL. This protein is not restricted to leukemic cells, however, and is found on a variety of normal tissues. The protein is a neutral endopeptidase that cleaves peptides at the amino side of hydrophobic residues and inactivates several peptide hormones including glucagon, enkephalins, substance P, neurotensin, oxytocin, and bradykinin.

Function:
Thermolysin-like specificity, but is almost confined on acting on polypeptides of up to 30 amino acids. Biologically important in the destruction of opioid peptides such as Met- and Leu-enkephalins by cleavage of a Gly-Phe bond. Able to cleave angiotensin-1, angiotensin-2 and angiotensin 1-9. Involved in the degradation of atrial natriuretic factor (ANF). Displays USLVinducible elastase activity toward skin preelastic and elastic fibers.
Subcellular Location:
Cell membrane; Single-pass type II membrane protein.
Post-translational modifications:
Myristoylation is a determinant of membrane targeting.
Glycosylation at Asn-628 is necessary both for surface expression and neutral endopeptidase activity.
Similarity:
Belongs to the peptidase M13 family.

CD10即共同型急性淋巴细胞白血病抗原,是II型跨膜糖蛋白.CD10表达于早期B淋巴细胞,某些粒性白细胞,骨髓基质细胞,部分上皮组织及其起源的肿瘤细胞中也有表达.主要应用于某些恶性淋巴瘤和白血病的分型.CD10是一种94kD的锌依赖性细胞膜金属结合蛋白，参与细胞神经肽和激素肽的后分泌过程。它广泛地分布于肾、肝、小肠、胎盘、脉络膜丛、脑腺、腺皮质和白细胞，CD10是生发中心细胞及所致淋巴瘤的标志物。
