Gene: Kcnb2 (potassium voltage-gated channel subfamily B member 2) Rattus norvegicus
Analyze
Symbol: Kcnb2
Name: potassium voltage-gated channel subfamily B member 2
RGD ID: 621349
Description: Enables delayed rectifier potassium channel activity; protein heterodimerization activity; and transmembrane transporter binding activity. Involved in potassium ion transmembrane transport and protein localization to plasma membrane. Located in dendrite and neuronal cell body membrane. Part of voltage-gated potassium channel complex. Human ortholog(s) of this gene implicated in alcohol dependence. Orthologous to human KCNB2 (potassium voltage-gated channel subfamily B member 2); INTERACTS WITH 17beta-estradiol; 6-propyl-2-thiouracil; acrylamide.
Type: protein-coding
RefSeq Status: PROVISIONAL
Previously known as: CDRK; Kv2.2; potassium channel, voltage gated Shab-related subfamily B, member 2; potassium voltage gated channel, Shab-related subfamily, member 2; voltage-gated potassium channel subunit Kv2.2
