What's a GeneRIF?

The authors identified a core heterodimeric complex of human small vasohibin-binding protein (SVBP) and vasohibin 1 (VASH1) that catalyzes the detyrosination of a peptide derived from C-terminus of alpha-tubulin.
Title: Molecular basis of vasohibins-mediated detyrosination and its impact on spindle function and mitosis.
This study examined the crystal structures of human vasohibin 1 and 2 in complex with small vasohibin-binding protein (SVBP) in the absence and presence of different inhibitors and a C-terminal alpha-tubulin peptide.
Title: Structural basis of tubulin detyrosination by the vasohibin-SVBP enzyme complex.
This study describes the crystal and solution structure of the tubulin carboxypeptidase complex between vasohibin (VASH1) and small vasohibin-binding protein (SVBP), which folds in a long helix, which stabilizes the VASH1 catalytic domain.

SVBP is not only involved in angiogenesis, but also has vital functions in the central nervous system. Biallelic loss-of-function variants in SVBP lead to intellectual disability.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
