Human CLIC4, His Tag (CL4-H5141) is expressed from E.coli cells. It contains AA Met 1 - Lys 253 (Accession # AAH12444).

Predicted N-terminus: Met

Molecular Characterization

CLIC4(Met 1 - Lys 253)AAH12444

This protein carries a polyhistidine tag at the N-terminus.

The protein has a calculated MW of 29.6 kDa. The protein migrates as 25-30 kDa under reducing (R) condition (SDS-PAGE).


Less than 1.0 EU per μg by the LAL method.


>92% as determined by SDS-PAGE.


Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Chloride intracellular channel protein 4 (CLIC4) ,a member of the chloride channel CLIC family, is also known as intracellular chloride ion channel protein p64H1,which contains one GST C-terminal domain. CLIC4 can insert into membranes and form poorly selective ion channels that may also transport chloride ions. Channel activity depends on the pH. Membrane insertion seems to be redox-regulated and may occur only under oxydizing conditions. Also,CLIC4 can promote cell-surface expression of HRH3, endothelial cell proliferation and regulate endothelial morphogenesis. Furthermore ,CLIC4 has alternate cellular functions like a potential role in angiogenesis or in maintaining apical-basolateral membrane polarity during mitosis and cytokinesis.
