 [[http://www.uniprot.org/uniprot/VASH1_HUMAN VASH1_HUMAN]] Tyrosine carboxypeptidase that removes the C-terminal tyrosine residue of alpha-tubulin, thereby regulating microtubule dynamics and function (PubMed:29146869). Acts as an angiogenesis inhibitor: inhibits migration, proliferation and network formation by endothelial cells as well as angiogenesis (PubMed:15467828, PubMed:16488400, PubMed:16707096, PubMed:19204325). This inhibitory effect is selective to endothelial cells as it does not affect the migration of smooth muscle cells or fibroblasts (PubMed:15467828, PubMed:16488400, PubMed:16707096).<ref>PMID:15467828</ref> <ref>PMID:16488400</ref> <ref>PMID:16707096</ref> <ref>PMID:19204325</ref> <ref>PMID:29146869</ref>  [[http://www.uniprot.org/uniprot/SVBP_HUMAN SVBP_HUMAN]] Enhances the tyrosine carboxypeptidase activity of VASH1 and VASH2, thereby promoting the removal of the C-terminal tyrosine residue of alpha-tubulin (PubMed:29146869).

+== Publication Abstract from PubMed ==
+Microtubules are regulated by post-translational modifications of tubulin. The ligation and cleavage of the carboxy-terminal tyrosine of alpha-tubulin impact microtubule functions during mitosis, cardiomyocyte contraction and neuronal processes. Tubulin tyrosination and detyrosination are mediated by tubulin tyrosine ligase and the recently discovered tubulin detyrosinases, vasohibin 1 and 2 (VASH1 and VASH2) bound to the small vasohibin-binding protein (SVBP). Here, we report the crystal structures of human VASH1-SVBP alone, in complex with a tyrosine-derived covalent inhibitor and bound to the natural product parthenolide. The structures and subsequent mutagenesis analyses explain the requirement for SVBP during tubulin detyrosination, and reveal the basis for the recognition of the C-terminal tyrosine and the acidic alpha-tubulin tail by VASH1. The VASH1-SVBP-parthenolide structure provides a framework for designing more effective chemical inhibitors of vasohibins, which can be valuable for dissecting their biological functions and may have therapeutic potential.
