RL Submitted (SEP-2000) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: pH-dependent, voltage-insensitive, background potassium
CC channel protein. Rectification direction results from potassium
CC ion concentration on either side of the membrane. Acts as an
CC outward rectifier when external potassium concentration is low.
CC When external potassium concentration is high, current is inward
CC (By similarity).
CC -!- SUBCELLULAR LOCATION: Integral membrane protein (By similarity).
CC -!- SIMILARITY: Belongs to the two pore domain potassium channel
CC (TC 1.A.1.8) family.
