| Specific Function
| Involved in 40S ribosomal subunit biogenesis and 18S rRNA processing. Specifically catalyzes the N1-methylation of pseudouridine at position 1248 (Psi1248) in 18S rRNA. Thus, appears to be the methyltransferase involved in the biosynthesis of the hypermodified N1-methyl-N3-(3-amino-3-carboxypropyl) pseudouridine (m1acp3-Psi) in position 1248 in 18S rRNA. Is not able to methylate uridine at this position.
