Protein

Guanylyl cyclase-activating protein 2

Gene
GUCA1B, GCAP2
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Stimulates guanylyl cyclase 1 (GC1) and GC2 when free calcium ions concentration is low, and GC1 and GC2 when free calcium ions concentration is elevated. This Ca2+-sensitive regulation of GC is a key event in recovery of the dark state of rod photoreceptors following light exposure.

Pathology & Biotechi

Involvement in diseasei

Retinitis pigmentosa 48 (RP48) [MIM:613827]: A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well.
Note: The disease is caused by mutations affecting the gene represented in this entry.1 Publication
