NAA10, N-alpha-acetyltransferase 10
Enzyme Classification 126.96.36.199
Also Known as
NAA10_HUMAN, NAA10, ARD1, ARD1A, TE2
Catalytic subunit of the N-terminal acetyltransferase A (NatA) complex which displays alpha (N-terminal) acetyltransferase activity (PubMed:15496142, PubMed:19826488, PubMed:19420222, PubMed:20145209, PubMed:27708256, PubMed:25489052). Acetylates amino termini that are devoid of initiator methionine (PubMed:19420222). The alpha (N-terminal) acetyltransferase activity may be important for vascular, hematopoietic and neuronal growth and development. Without NAA15, displays epsilon (internal) acetyltransferase activity towards HIF1A, thereby promoting its degradation (PubMed:12464182). Represses MYLK kinase activity by acetylation, and thus represses tumor cell migration (PubMed:19826488). Acetylates, and stabilizes TSC2, thereby repressing mTOR activity and suppressing cancer development (PubMed:20145209). Acetylates HSPA1A and HSPA1B at 'Lys-77' which enhances its chaperone activity and leads to preferential binding to co-chaperone HOPX (PubMed:27708256). Acts as a negative regulator of sister chromatid cohesion during mitosis (PubMed:27422821). Component of the N-terminal acetyltransferase A (NatA) complex composed of NAA10 and NAA15 or NAA16 (PubMed:20154145). Interacts with HIF1A (via its ODD domain); the interaction increases HIF1A protein stability during normoxia, an down-regulates it when induced by hypoxia (PubMed:12464182). Interacts with NAA50 and with the ribosome (PubMed:16507339). Binds to MYLK (PubMed:19826488). Associates with HYPK when in complex with NAA15 (PubMed:15496142). Interacts with NAA15 (PubMed:15496142). Interacts with NAA16 (PubMed:19480662). Interacts (via its C-terminal domain) with TSC2, leading to its acetylation (PubMed:20145209). Interacts with NAA16 (PubMed:19480662). Interacts with IKBKB (PubMed:19716809). Interacts with HSPA1A and HSPA1B leading to its acetylation (PubMed:27708256).
