Protein-coding gene in the species Homo sapiens
Chloride intracellular channel 4 , also known as CLIC4 ,p644H1 ,HuH1 , is a eukaryotic gene .[5]
Chloride channels are a diverse group of proteins that regulate fundamental cellular processes including stabilization of cell membrane potential, transepithelial transport, maintenance of intracellular pH , and regulation of cell volume. Chloride intracellular channel 4 (CLIC4) protein, encoded by the clic4 gene, is a member of the p64 family; the gene is expressed in many tissues. These channels are implicated in angiogenesis , pulmonary hypertension , cancer , and cardioprotection from ischemia-reperfusion injury . They exhibit an intracellular vesicular pattern in PANC-1 cells (pancreatic cancer cells).[5]
CLIC4 binds to dynamin I, α-tubulin , β-actin , creatine kinase and two 14-3-3 isoforms.[6]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
