Protein kinase C; part of cell wall integrity (CWI) signaling pathway composed of pkcA, the bck1-mkk2-mpka MAPK cascade and the downstream rlmA transcription regulator (PubMed:26295576, PubMed:27473315). The CWI signaling pathway regulates cell wall integrity and pyomelanin formation (PubMed:26295576). CWI controls also oxidative stress response, gliotoxin production, iron adaptation and asexual development (PubMed:26295576, PubMed:32005734). Finally, CWI is constitutively required for A.fumigatus to cope with the temperature increase found in the mammalian lung environment, during infection (PubMed:33010083). Modulates the expression of fumiquinazoline cluster during conidiogenesis (PubMed:33705521). ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-[protein] ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-threonyl-[protein] Interacts with hsp90. Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. PKC subfamily.
