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. Required during mitosis for normal bipolar spindle formation and
CC chromosome segregation via its action on target proteins.
CC {ECO:0000250|UniProtKB:Q9BV86}.
