(redirected from eag1)

KCNH1

A gene on chromosome 1q32.2 that encodes a pore-forming alpha subunit of the voltage-gated, potassium channel subfamily H, which is part of a non-inactivating delayed rectifier potassium channel. It is activated in the embryo with myoblast differentiation; it is highly expressed in brain and in myoblasts.

Molecular pathology
KCNH1 is overexpressed in some cancers.

The metal oxide is zinc oxide; the covering layer is a sacrificial metal; and the thicknesses (eAg1, eAg2, eAg3) of the silver layers (Ag1, Ag2, Ag3) vary in a ratio of between 0.8 and 1.2 and are such that eAg1 [less than or equal to] eAg3 [less than or equal to] eAg2 and eAg1 corresponds to the thickness of the silver layer closest to the substrate and eAg3 corresponds to the thickness of the silver layer furthest from the substrate.
