[Term] id: PR:000045378 name: cGMP-gated cation channel alpha-1 isoform 1 phosphorylated 2 def: "A cGMP-gated cation channel alpha-1 isoform 1 phosphorylated form in which the phosphorylation occurs at the Tyr residue within the VYSPGD motif located at the N terminus of the cyclic-nucleotide binding domain (CNDB) and the residue at the position equivalent to Tyr-503 of the amino acid sequence represented by UniProtKB:Q00194-1. This phosphorylation prevents Ca2+/CaM inhibition of the CNG channel, but at the same time has a similar effect, that is decreases the apparent affinity for cGMP. Example: UniProtKB:Q00194-1, Tyr-498/Tyr-503, MOD:00048."
