Tyrosine carboxypeptidase that removes the C-terminal tyrosine residue of alpha-tubulin, thereby regulating microtubule dynamics and function (PubMed:29146869). Critical for spindle function and accurate chromosome segregation during mitosis since microtuble detyronisation regulates mitotic spindle length and postioning (PubMed:31171830). Acts as an activator of angiogenesis: expressed in infiltrating mononuclear cells in the sprouting front to promote angiogenesis (PubMed:19204325). Plays a role in axon formation (PubMed:31235911). C-terminal L-alpha-aminoacyl-L-glutamyl-L-glutamyl-L-tyrosyl-[tubulin] + H2O = C-terminal L-alpha-aminoacyl-L-glutamyl-L-glutamyl-[tubulin] + L-tyrosine Interacts with SVBP; interaction enhances VASH2 tyrosine carboxypeptidase activity. Mainly localizes in the cytoplasm (PubMed:19204325). Some fraction is secreted via a non-canonical secretion system; interaction with SVBP promotes secretion (PubMed:20736312). Associates with microtubules (PubMed:31235911). Expressed in various embryonic organs at 6 to 12 embryonic weeks. Detected in vessels from 20-week embryonic organs as well as in endothelial cells from large vessels in neonate. By VEGF. Belongs to the transglutaminase-like superfamily. Vasohibin family.
