Type: | Family | Name: | PIH1 family |
Description: | Proteins in this family contain PIH1 domains. This family consists of the kintoun, Saccharomyces cerevisiae PIH1 (protein interacting with Hsp90 1, also known as Nop17) and PIH1 domain-containing proteins. Kintoun is required for cytoplasmic pre-assembly of axonemal dyneins, thereby playing a central role in motility in cilia and flagella. It involved in pre-assembly of dynein arm complexes in the cytoplasm before intraflagellar transport loads them for the ciliary compartment [].PIH1 is a component of the conserved R2TP complex (Rvb1-Rvb2-Tah1-Pih1), which interacts with Hsp90 to mediate assembly large protein complexes such as box C/D snoRNPs and RNA polymerase II []. PTH1 is also involved in pre-rRNA processing and required for the NOP58-snoRNA interaction []. | Short Name: | PIH1 |
