Connexin43 (Cx43) one of the most widely expressed and abundant vertebrate space junction protein is phosphorylated at multiple different serine residues during its existence cycle. P1 isoform an event that apparently regulates trafficking to or within the plasma membrane. Phosphorylation at S325 328 and/or 330 is necessary to form a P2 isoform and this phosphorylation… Continue reading Connexin43 (Cx43) one of the most widely expressed and abundant vertebrate
