Target Information
SPACA3 (sperm acrosome associated 3), also known as sperm lysozyme-like protein 1, lysozyme-like protein 3, lysozyme-like acrosomal sperm-specific secretory protein ALLP-17, cancer/testis antigen 54 (CT54), LYC3, SPRASA, or LYZL3, is a 215 amino acid protein that participates in the fusion and adhesion of sperm and egg plasma membrane during fertilization.
It has been identified as a novel cancer/testis antigen in hematologic malignancies and can elicit B-cell immune responses in cancer patients, making it a potential target for immunotherapy.
A member of the glycosyl hydrolase 22 family, SPACA3 is expressed in testis, placenta, and epididymis. It exists as two alternatively spliced isoforms: isoform 1 (single-pass type II membrane protein of sperm acrosome) and isoform 2 (secreted protein).
SPACA3 may be involved in sperm-egg plasma membrane adhesion and fusion during fertilization and could act as a receptor for egg oligosaccharide residue N-acetylglucosamine. The processed form shows no detectable bacteriolytic activity in vitro.
