Gene: Dkc1 (dyskerin pseudouridine synthase 1) Rattus norvegicus
Symbol: Dkc1
Name: dyskerin pseudouridine synthase 1
RGD ID: 621780
Description: Predicted to enable box H/ACA snoRNA binding activity; pseudouridine synthase activity; and telomerase RNA binding activity. Predicted to contribute to telomerase activity. Involved in positive regulation of cell population proliferation and snoRNA guided rRNA pseudouridine synthesis. Located in Cajal body and nucleolus. Part of box H/ACA snoRNP complex. Human ortholog(s) of this gene implicated in X-linked dyskeratosis congenita; aplastic anemia; and dyskeratosis congenita. Orthologous to human DKC1 (dyskerin pseudouridine synthase 1); PARTICIPATES IN ribosome biogenesis pathway; INTERACTS WITH (+)-schisandrin B; 2,3,7,8-tetrachlorodibenzodioxine; 2,3,7,8-Tetrachlorodibenzofuran.
Type: protein-coding
Previously known as: dyskeratosis congenita 1, dyskerin; dyskerin; h/ACA ribonucleoprotein complex subunit 4; H/ACA ribonucleoprotein complex subunit DKC1; Nap57; nopp140-associated protein of 57 kDa; nucleolar protein family A member 4; nucleolar protein NAP57; snoRNP protein DKC1
