NRMT, NTM1A, AD-003, HOMT1A, C9orf32, METTL11A, N-terminal Xaa-Pro-Lys N-methyltransferase 1, Alpha N-terminal protein methyltransferase 1A, Methyltransferase-like protein 11A, N-terminal RCC1 methyltransferase, X-Pro-Lys N-terminal protein methyltransferase 1A, NTMT1, NRMT1
Distributive alpha-N-methyltransferase that methylates the N-terminus of target proteins containing the N-terminal motif [Ala/Pro/Ser]-Pro-Lys when the initiator Met is cleaved. Specifically catalyzes mono-, di- or tri-methylation of exposed alpha-amino group of Ala or Ser residue in the [Ala/Ser]-Pro-Lys motif and mono- or di-methylation of Pro in the Pro-Pro-Lys motif. Some of the substrates may be primed by METTL11B-mediated monomethylation. Responsible for the N-terminal methylation of KLHL31, MYL2, MYL3, RB1, RCC1, RPL23A and SET. Required during mitosis for normal bipolar spindle formation and chromosome segregation via its action on RCC1.
