Threonine 73-82 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 28-35 9029728-14 1997 Alternatively, the affinity of P450c17 for redox partners may be selectively increased by Ser/Thr phosphorylation, or selectively decreased by certain mutations in the redox partner binding site, in either case altering an electrostatic interaction between P450c17 and the redox partner. Threonine 94-97 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 31-38 20160131-4 2010 One factor favoring more efficient electron transfer and 17,20 lyase activity is cAMP-dependent serine/threonine phosphorylation of P450c17. Threonine 103-112 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 132-139 20534731-10 2010 Time-course experiments revealed that a short cAMP stimulation augmented threonine phosphorylation of P450c17 but did not increase 17,20-lyase activity. Threonine 73-82 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 102-109 7479852-3 1995 We show that human P450c17 is phosphorylated on serine and threonine residues by a cAMP-dependent protein kinase. Threonine 59-68 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 19-26 8504753-4 1993 We used site-directed mutagenesis to construct expression vectors for the conservative P450c17 mutations Ser106-->Thr and Ser106-->Ala. Threonine 117-120 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 87-94 25224484-5 2015 Third, the serine/threonine phosphorylation of P450c17 itself promotes 17,20 lyase activity, again apparently by promoting the interaction of P450c17 with POR. Threonine 18-27 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 47-54 25224484-5 2015 Third, the serine/threonine phosphorylation of P450c17 itself promotes 17,20 lyase activity, again apparently by promoting the interaction of P450c17 with POR. Threonine 18-27 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 142-149 23836902-3 2013 These are increased amounts of POR, the allosteric action of cytochrome b5 to promote POR-P450c17 interaction, and Ser/Thr phosphorylation of P450c17, which also appears to promote POR-P450c17 interaction. Threonine 119-122 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 142-149 23836902-3 2013 These are increased amounts of POR, the allosteric action of cytochrome b5 to promote POR-P450c17 interaction, and Ser/Thr phosphorylation of P450c17, which also appears to promote POR-P450c17 interaction. Threonine 119-122 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 142-149 20160131-8 2010 Using this vector, we explored P450c17 phosphorylation by mutagenesis of Ser and/or Thr residues to Asp or Glu to mimic the approximate size and charge of phospho-Ser or phospho-Thr. Threonine 84-87 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 31-38 16616104-0 2006 Mutagenesis of putative serine-threonine phosphorylation sites proximal to Arg255 of human cytochrome P450c17 does not selectively promote its 17,20-lyase activity. Threonine 31-40 cytochrome P450 family 17 subfamily A member 1 Homo sapiens 91-109 16616104-1 2006 OBJECTIVE: To investigate the role of serine-threonine phosphorylation on the activity of human P450c17.
