Inwardly rectifying k+ channels
WebTarget Information: 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. It is activated by internal ATP and probably plays an important role in potassium homeostasis.

WebInwardly rectifying K+ channels (Kir channels) show an inward rather than outward (like the voltage gated K+ channels) flow of K+ thereby contributing to maintenance of … WebProperties of inwardly rectifying K + channels in small-cell lung cancer (SCLC) cells have not been clarified in detail. Here, we found inwardly rectifying K + channels in a human SCLC cell line (RERF-LC-MA), which expresses no multidrug resistance-associated protein 1 (MRP1) and multidrug resistance P-glycoprotein (MDR1).
WebThe TWIK-related spinal cord potassium channel (TRESK) is encoded by KCNK18, and variants in this gene have previously been associated with susceptibility to familial migraine with aura (MIM #613656). A single amino acid substitution in the same protein, p.Trp101Arg, has also been associated with intellectual disability (ID), opening the possibility that … WebFunción.

WebIt is thought that the membrane potential of sperm hyperpolarizes during capacitation, possibly due to the opening of K + channels, but electrophysiological evidence is lacking. In this report, using patch-clamp recordings obtained from isolated mouse spermatogenic cells we document the presence of a novel K + -selective inwardly rectifying current.
