The function of ENSG00000145996 (CDKAL1, CDKAL1 threonylcarbamoyladenosine tRNA methylthiotransferase) is as follows. Catalyzes the methylthiolation of N6- threonylcarbamoyladenosine (t(6)A), leading to the formation of 2- methylthio-N6-threonylcarbamoyladenosine (ms(2)t(6)A) at position 37 in tRNAs that read codons beginning with adenine. .
