Catalyzes the 2 serial methylation steps for the conversion of the 7-monomethylguanosine (m(7)G) caps of snRNAs and snoRNAs to a 2,2,7-trimethylguanosine (m(2,2,7)G) cap structure The enzyme is specific for guanine, and N7 methylation must precede N2 methylation. Hypermethylation of the m7G cap of U snRNAs leads to their concentration in nuclear foci, their colocalization with coilin and the formation of canonical Cajal bodies (CBs). Plays a role in transcriptional regulation
Tissue Specificity
Ubiquitously expressed. High expression in heart, skeletal muscle, kidney, liver and placenta
Cellular Localization
Cytoplasm. Nucleus, Cajal body. Note=A 90 kDa isoform is found in the nucleus while a 55 kDa isoform is found in the cytoplasm and colocalizes with the tubulin network
Western blot analysis of hNCOA6IP N-term D5 in NIH-3T3 cell line lysates (35ug/lane). NCOA6IP (arrow) was detected using the purified Pab.
