Summaries for KCNV2 Gene

Entrez Gene Summary for KCNV2 Gene

  • Voltage-gated potassium (Kv) channels represent the most complex class of voltage-gated ion channels from both functional and structural standpoints. Their diverse functions include regulating neurotransmitter release, heart rate, insulin secretion, neuronal excitability, epithelial electrolyte transport, smooth muscle contraction, and cell volume. This gene encodes a member of the potassium voltage-gated channel subfamily V. This member is identified as a 'silent subunit', and it does not form homomultimers, but forms heteromultimers with several other subfamily members. Through obligatory heteromerization, it exerts a function-altering effect on other potassium channel subunits. This protein is strongly expressed in pancreas and has a weaker expression in several other tissues. [provided by RefSeq, Jul 2008]

GeneCards Summary for KCNV2 Gene

KCNV2 (Potassium Channel, Voltage Gated Modifier Subfamily V, Member 2) is a Protein Coding gene. Diseases associated with KCNV2 include retinal cone dystrophy 3b and cone dystrophy with supernormal rod response. Among its related pathways are Activation of cAMP-Dependent PKA and Activation of cAMP-Dependent PKA. GO annotations related to this gene include delayed rectifier potassium channel activity. An important paralog of this gene is KCNB2.

UniProtKB/Swiss-Prot for KCNV2 Gene

  • Potassium channel subunit. Modulates channel activity by shifting the threshold and the half-maximal activation to more negative values

Tocris Summary for KCNV2 Gene

  • Voltage-gated potassium channels (KV) belong to the 6-TM family of potassium channel that also comprises the Ca2+-activated Slo (actually 7-TM) and the Ca2+-activated SK subfamilies. The pore-forming alpha-subunits contain a single pore-forming region and combine to form tetramers. Heteromeric channels can be formed within subfamilies e.g. KV1.1 with KV1.2 and KCNQ2 with KCNQ3.

  • Cone dystrophy retinal 3B (RCD3B) [MIM:610356]: A rare form of cone dystrophy associated with supernormal rod responses. The disorder is characterized by reduced visual acuity, photoaversion, night blindness, and abnormal color vision. At an early age, the retina shows subtle depigmentation at the macula and, later, more obvious areas of atrophy. {ECO:0000269 PubMed:16909397}. Note=The disease is caused by mutations affecting the gene represented in this entry.
