NAD-dependent protein deacetylase sirtuin-2

Gene

Organism
Danio rerio (Zebrafish) (Brachydanio rerio)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

NAD-dependent protein deacetylase, which deacetylates internal lysines on histone and alpha-tubulin as well as many other proteins such as key transcription factors (By similarity). Participates in the modulation of multiple and diverse biological processes such as cell cycle control, genomic integrity, microtubule dynamics, cell differentiation, metabolic networks, and autophagy. Plays a major role in the control of cell cycle progression and genomic stability. Deacetylates histone H4 at 'Lys-16' (H4K16ac) at the VEGFA promoter. Thereby contributes to regulate expression of vegfa, a key regulator of angiogenesis (PubMed:24940000).By similarity1 Publication
