This family of proteins function as angiogenesis inhibitors in animals [1-2]. Reversible detyrosination of alpha-tubulin is crucial to microtubule dynamics and functions and defects have been implicated in cancer, brain disorganization, and cardiomyopathies. VASH1 and its homolog VASH2, when complexed with SVBP, exhibited robust and specific Tyr/Phe carboxypeptidase activity on microtubules [4].
