DESCRIPTION

Also known as PIHD1_HUMAN, PIH1D1, NOP17. Involved in the assembly of C/D box small nucleolar ribonucleoprotein (snoRNP) particles (PubMed:17636026). Recruits the SWI/SNF complex to the core promoter of rRNA genes and enhances pre-rRNA transcription (PubMed:22368283, PubMed:24036451). Mediates interaction of TELO2 with the R2TP complex which is necessary for the stability of MTOR and SMG1 (PubMed:20864032). Positively regulates the assembly and activity of the mTORC1 complex (PubMed:24036451). Component of the R2TP complex composed at least of RUVBL1, RUVBL2, RPAP3 and PIHD1 (PubMed:20864032). Component of the PAQosome complex which is responsible for the biogenesis of several protein complexes and which consists of R2TP complex members RUVBL1, RUVBL2, RPAP3 and PIH1D1, URI complex members PFDN2, PFDN6, PDRG1, UXT and URI1 as well as ASDURF, POLR2E and DNAAF10/WDR92 (PubMed:31738558). Interacts with phosphorylated TELO2 and mediates interaction of TELO2 with the R2TP complex (PubMed:20864032, PubMed:24656813). Interacts with phosphorylated ECD, EFTUD2/SNRP116, RPB1 and UBR5 and with RPB1 in a phosphorylation-independent manner (PubMed:24656813). Interacts with the core C/D box snoRNP particle components NOP58 and FBL and with RUVBL1/TIP49 (PubMed:17636026). Interacts with RPAP3 and DNAAF10 (PubMed:21078300). Interacts with histone H4 and with SWI/SNF complex member SMARCB1/SNF5 (PubMed:22368283). Interacts with the mTORC1 complex member RPTOR (PubMed:24036451). Interacts with MSL1 (By similarity).
