Gene: PRPS1 (phosphoribosyl pyrophosphate synthetase 1) Homo sapiens
Symbol: PRPS1
Name: phosphoribosyl pyrophosphate synthetase 1
Description: Exhibits ATP binding activity; protein homodimerization activity; and ribose phosphate diphosphokinase activity. Involved in nervous system development and purine-containing compound biosynthetic process. Predicted to localize to the cytoplasm and ribose phosphate diphosphokinase complex. Implicated in Arts syndrome; X-linked nonsyndromic deafness; X-linked recessive disease (multiple); gout; and retinitis pigmentosa.
Type: protein-coding
RefSeq Status: REVIEWED
