Soluble guanylate cyclases are heterodimeric proteins that catalyze the conversion of GTP to 3',5'-cyclic GMP and pyrophosphate. The protein encoded by this gene is an alpha subunit of this complex and it interacts with a beta subunit to form the guanylate cyclase enzyme, which is activated by nitric oxide. Several transcript variants encoding a few different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]
GeneCards Summary for GUCY1A3 Gene
GUCY1A3 (Guanylate Cyclase 1, Soluble, Alpha 3) is a Protein Coding gene. Diseases associated with GUCY1A3 include moyamoya 6 with achalasia and moyamoya disease with early-onset achalasia. Among its related pathways are CREB Pathway and Nanog in Mammalian ESC Pluripotency. GO annotations related to this gene include GTP binding and heme binding. An important paralog of this gene is ADCY5.
Guanylyl Cyclases (GC) are a group of enzymes that, in the presence of a metal ion co-factor such as Mg2+ or Mn2+, convert guanosine-5'-triphosphate (GTP) into 3',5'-guanosine monophosphate (cGMP) and pyrophosphate. The second messenger cGMP participates in signaling by stimulating protein kinase G enzymes, altering the conductance of cGMP-gated ion channels and changing the activity of cGMP-regulated phosphodiesterases. There are two main groups of guanylyl cyclase; soluble GC (sGC), which are the receptor for nitric oxide (NO) and transmembrane GC (pGC), which serves as a receptor for natriuretic peptides. Key physiological roles for guanylyl cyclases include regulation of cell hyperplasia, hypertrophy, migration, extracellular matrix production, cell differentiation and tumor progression. In addition, guanylyl cyclases mediate important communication between the heart, intestine and kidney to regulate blood volume and Na+ balance.
