Grouped By:  Matching UniProtKB accession

UniProtKB description:  Plays an important role in regulating cell division and growth by reversible phosphorylation signaling (PubMed:14575702, PubMed:12950916, PubMed:27758870). May play important roles in regulating cellular metabolism and signaling pathways, which could mediate the growth and development of the cell (PubMed:31958639). Plays a role in establishing and maintaining infection (PubMed:27758870). Dephosphorylates several proteins, including the kinases PknA, PknB, PknD, PknE, PknF, PknH, PknJ and Pyk, the transcriptional regulatory proteins EmbR and EthR, the osmosensory protein OprA and the dimycocerosyl transferase PapA5 (PubMed:14575702, PubMed:12950916, PubMed:15967413, PubMed:16817899, PubMed:17411339, PubMed:19826007, PubMed:20520732, PubMed:21423706, PubMed:31958639). In vitro, dephosphorylates the phosphorylated Ser/Thr residues of myelin basic protein (MBP), histone and casein phosphorylated at Ser/Thr residues, but fails to dephosphorylate phosphotyrosine residue of these substrates (PubMed:14575702, PubMed:12950916).
