CC -!- FUNCTION: Distributive alpha-N-methyltransferase that methylates the N-
CC terminus of target proteins containing the N-terminal motif
CC [Ala/Gly/Pro/Ser]-Pro-Lys when the initiator Met is cleaved.
CC Specifically catalyzes mono-, di- or tri-methylation of the exposed
CC alpha-amino group of the Ala, Gly or Ser residue in the [Ala/Gly/Ser]-
CC Pro-Lys motif and mono- or di-methylation of Pro in the Pro-Pro-Lys
CC motif. Some of the substrates may be primed by NTMT2-mediated
CC monomethylation. Catalyzes the trimethylation of the N-terminal Gly in
CC CENPA (after removal of Met-1). Responsible for the N-terminal
CC methylation of KLHL31, MYL2, MYL3, RB1, RCC1, RPL23A and SET. Required
CC during mitosis for normal bipolar spindle formation and chromosome
CC segregation via its action on RCC1. {ECO:0000250|UniProtKB:Q9BV86}.
