| 背景： | Chloride intracellular channel (CLIC) is a family of proteins encoded by six different genes (CLIC1-6)1-3.The localization of the various CLIC channels remains elusive and controversial since they can be either found in a soluble form in the cytoplasm or as integral membrane proteins (in intracellular compartments such as the nuclear membrane or the endoplasmic reticulum for example, or associate to the plasma membrane) via their single transmembrane domain1.When membrane associated, CLIC channels indeed function as ion channels (enabling the passage of Cl- ions). Non-channel functions are also attributed to CLICs and include cell cycle regulation, cell differentiation, and apoptosis. These different roles depend whether CLICs are membrane bound or cytosolic1. For instance, CLIC4 is involved in keratinocyte differentiation in a TGFb-dependent manner4,5, in such a way that TGFb stimulation induces the expression and nuclear localization of CLIC4 and its subsequent interaction with transcription factors4. CLIC4 is also required for growth arrest and apoptosis under stress6.CLIC4 distribution is rather ubiquitous but shows higher expression level in skin, kidney, brain and testes7.Alomone Labs is pleased to offer a highly specific antibody directed against an epitope of human CLIC4. Anti-CLIC4 antibody (#AG1305) can be used in western blot and immunocytochemistry applications and has been designed to recognize CLIC4 from mouse, rat and human samples.REFERENCESReferences 1.
