CC   -!- FUNCTION: Component of the EKC/KEOPS complex that is required for the
CC       formation of a threonylcarbamoyl group on adenosine at position 37
CC       (t(6)A37) in tRNAs that read codons beginning with adenine. The complex
CC       is probably involved in the transfer of the threonylcarbamoyl moiety of
CC       threonylcarbamoyl-AMP (TC-AMP) to the N6 group of A37. CGI121 acts as
CC       an allosteric effector that regulates the t(6)A activity of the
CC       complex. The EKC/KEOPS complex also promotes both telomere uncapping
CC       and telomere elongation. The complex is required for efficient
CC       recruitment of transcriptional coactivators. CGI121 is not required for
CC       tRNA modification (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Component of the EKC/KEOPS complex composed of at least BUD32,
CC       CGI121, GON7, KAE1 and PCC1; the whole complex dimerizes.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Chromosome, telomere
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the CGI121/TPRKB family. {ECO:0000305}.
