Anti-CRISPLD2 antibodies are used in the immunodetection of the protein cysteine rich secretory protein LCCL domain containing 2. In humans, the canonical protein has a reported length of 497 amino acid residues and a mass of 55.9 kDa. It is known to be a secreted protein. Alternative splicing is reported to yield 5 different isoforms for this protein. A member of a the CRISP protein family, CRISPLD2 is reported to promote matrix assembly. Post-translational modifications have been described, including glycosylation. Synonyms for this target antigen include LCCL domain-containing cysteine-rich secretory protein 2, cysteine-rich secretory protein 11, late gestation lung 1, testis secretory sperm-binding protein Li 207a, trypsin inhibitor, and CRISP-11.
