CELE_C47B2.2

C47B2.2 encodes, by alternative splicing, two isoforms of a uracil phosphoribosyltransferase (UPRTase) homolog, orthologous to human UPRT (OMIM:300656) and budding yeast Fur1p; however, C47B2.2 lacks two normally conserved residues in its putative uracil-binding domain, and is thus predicted (like human UPRT) to lack UPRTase activity; C47B2.2's actual substrates are unknown.
