Superoxides 86-90 La ribonucleoprotein domain family, member 7 Mus musculus 43-48 32017896-4 2020 Mechanistically, LARP7 promotes U6 loading onto box C/D snoRNP, facilitating U6 2"-O-methylation by box C/D snoRNP. Superoxides 80-84 La ribonucleoprotein domain family, member 7 Mus musculus 17-22 32017896-5 2020 Importantly, ablation of LARP7 in the male germline causes defective U6 2"-O-methylation, massive alterations in pre-mRNA splicing, and spermatogenic failure in mice, which can be rescued by ectopic expression of wild-type LARP7 but not an U6-loading-deficient mutant LARP7. Superoxides 72-76 La ribonucleoprotein domain family, member 7 Mus musculus 25-30 32017896-6 2020 Our data uncover a novel role of LARP7 in regulating U6 2"-O-methylation and demonstrate the functional requirement of such modification for splicing fidelity and spermatogenesis in mice.
