GUCY1A2

Function

Has guanylyl cyclase on binding to the beta-1 subunit.

Isoform 2 acts as a negative regulator of guanylyl cyclase activity as it forms non-functional heterodimers with the beta subunits.

Sequence Similarities

Belongs to the adenylyl cyclase class-4/guanylyl cyclase family.

Tissue Specificity

Isoform 1 is expressed in fetal brain, liver, colon, endothelium and testis. Isoform 2 is expressed only in liver, colon and endothelium.

Cellular localization

Alternative names

GUC1A2, GUCSA2, GUCY1A2, Guanylate cyclase soluble subunit alpha-2, GCS-alpha-2
