Summary: Contributes to ribose phosphate diphosphokinase activity. Involved in 5-phosphoribose 1-diphosphate biosynthetic process. Located in cytoplasm. Part of ribose phosphate diphosphokinase complex. Used to study Arts syndrome; Charcot-Marie-Tooth disease X-linked recessive 5; and X-linked nonsyndromic deafness. Orthologous to human PRPSAP1 (phosphoribosyl pyrophosphate synthetase associated protein 1) and PRPSAP2 (phosphoribosyl pyrophosphate synthetase associated protein 2).

What's a GeneRIF?

Deletion of 284KKCPK288 pentameric motif from Prs3 destabilises the Prs1/Prs3 complex resulting in a cascade of events, including reduction in phosphoribosyl pyrophosphate synthetase activity and altered cell wall integrity (CWI) as measured by caffeine sensitivity and Rlm1 expression.
Title: The NHR1-1 of Prs1 and the pentameric motif 284KKCPK288 of Prs3 permit multi-functionality of the PRPP synthetase in Saccharomyces cerevisiae.
In addition to interacting with Prs3, Prs1 also interacts with Slt2, the MAPK of the cell wall integrity (CWI) pathway.
Title: The contribution of the nonhomologous region of Prs1 to the maintenance of cell wall integrity and cell viability.

NP_012740.1

EC 2.7.6.1

5-phospho-ribosyl-1(alpha)-pyrophosphate synthetase; synthesizes PRPP, which is required for nucleotide, histidine, and tryptophan biosynthesis; plays a key role in cell wall integrity (CWI) pathway; one of five related enzymes, which are active as heteromultimeric complexes; missense mutations in human homolog PRPS1 are associated with neuropathic Arts syndrome and Charcot-Marie Tooth (CMTX5) disease
