    basic FUNCTION
  • relaxing vascular smooth muscle and inhibiting platelet aggregation
  • significant role in the control of smooth muscle function in human penile erectile tissue
  • key regulator of cardiovascular physiology and pathology
  • its activity prevents pathological-level nitric oxide-induced apoptosis and promotes DNA synthesis/cell proliferation in vascular smooth muscle cells
  • key mediator of the nitric oxide/cGMP signaling pathway and plays a central role in regulating cardiovascular and neuronal functions
  • modulates glucagon release from pancreatic alpha-cells
  • serves as an integral component of second messenger signaling in a number of biological contexts including cell differentiation, memory, and vasodilation
    a component
  • important behavioral and physiological functions for the GUCY2C/PRKG1 signaling pathway within the brain
    small molecule
  • with RGS2
  • interacting with TP53 (TP53-dependent expression of PRKG1 is required for the ability of cGMP to counteract growth cone collapse)
  • exerts dual regulation of cardiac KCNJ channels
  • PRKG1 interacts with and phosphorylates rhotekin, thereby contributing to neurite outgrowth regulation
  • DAPK2 is likely one of the targets of PRKG1 in apoptosis induction
  • PRKG1 is a novel regulator of AR-mediated transcription by enhancing AR cofactor WDR77 function, which provide a novel mechanism for the growth regulation of prostate cancer cells by the androgen signaling
  • PRKG1 is a potent negative modulator of cardiac systolic mechanosignaling that requires TRPC6 as the target effector
  • cell & other
    Other its expression is subjected to post-transcriptional regulation in vascular smooth muscle cells through the 3 prime UTR of its mRNA
    TP53 is a transcription factor that regulates the expression of PRKG1 during neuronal maturation and cGMP-dependent inhibition of growth cone collapse
