Target Background

Major selective outward-rectifying potassium channel of the guard cell membrane. Involved in regulation of stomatal movements according to the water status. Assuming opened or closed conformations in response to the voltage difference across the membrane, the channel is activated by depolarization. Conductance of the channel is modulated in a potassium-dependent fashion. May interact with the cytoskeleton or with regulatory proteins.
Gene References into Functions
  1. Plants lacking functional GORK channels are more capable of retaining K+ for their better performance under hypoxia, and that RBOHD is crucial in hypoxia-induced Ca2+ signalling for stress sensing and acclimation mechanism. PMID: 28338729
  2. GORK is regulated by CPK33 PMID: 28543075
  3. GORK clustering in puncta is related to its gating and conductance, and reflects associated conformational changes and (de)stabilisation of the channel protein. PMID: 24517091
  4. Sustained activation of K+ outward current could be the result of an unexpected post-transcriptional regulation of the guard cell outward-rectifying K+ (GORK) channels. PMID: 23517047
Subcellular Location
Membrane; Multi-pass membrane protein.
Protein Families
Potassium channel family, Plant (TC 1.A.1.4) subfamily
Tissue Specificity
Expressed in guard cell-containing tissues, in root epidermal cells and in root hairs. Detected in vascular cells of the root and shoot.
