Anti-Vasohibin 1 antibodies are used in the immunodetection of the protein encoded by the VASH1 gene. In humans, the canonical protein has a reported length of 365 amino acid residues and a mass of 41 kDa. Its subcellular localization is in the cytoplasm and is also secreted. Alternative splicing is reported to yield 2 different isoforms for this protein. It is found to be highly expressed in endothelial cells. A member of the Vasohibin protein family, it is reported to be a tyrosine carboxypeptidase that removes the C-terminal tyrosine residue of alpha-tubulin, thereby regulating microtubule dynamics and function. Post-translational modifications have been described, including ubiquitination and protein cleavage. Other names for this target antigen include TTCP 1, tubulinyl-Tyr carboxypeptidase 1, tubulin carboxypeptidase 1, tyrosine carboxypeptidase 1, and KIAA1036.
