Phosphorylation of connexin-32 by protein kinase C prevents its proteolysis by mu-calpain and m-calpain. |In agreement with other authors (see Saez et al., 1990b), we have found that phosphorylation of connexin-32 by protein kinase A and protein kinase C occurs in serine residues, although we have detected trace amounts of phosphothreonine in connexin-32 phosphorylated by protein kinase C (results not shown). Indeed, Se233 has been shown to be the major phosphorylation site catalyzed by protein kinase A. However, Ser233, Ser239, and perhaps other serines are phosphorylated by protein kinase C (Saez et al., 1990b). |

connexin- 32 is proteolyzed by pcalpain and mcalpain. phosphorylation of connexin-32 by protein kinase C, but not by protein kinase A, efficiently prevents its proteolysis by both calpain isoforms. major phosphorylation sites: Ser233(for protein kinase A). Phosphorylation of connexin-32 by protein kinase C,but not by protein kinase A, prevents the proteolytic attack of p-calpain and m-calpain. Phosphorylation of connexin-32 by protein kinase A and protein kinase C does not prevent its proteolysis by papain, a-chymotrypsin, proteinase K, and trypsin |
