KCNJ2: Potassium inwardly rectifying channel subfamily J member 2
Gene ID
3759
General Description
Potassium channels are present in most mammalian cells, where they participate in a wide range of physiologic responses. The protein encoded by this gene is an integral membrane protein and inward-rectifier type potassium channel. The encoded protein, which has a greater tendency to allow potassium to flow into a cell rather than out of a cell, probably participates in establishing action potential waveform and excitability of neuronal and muscle tissues.

Function of the protein in oral and tooth development

Fatemifar et al.,(2013) conducted genome-wide association study and reported association of six loci with primary tooth eruption including KCNJ2/KCNJ16, IGF2BP1, and EDA.
