应用说明WB: Use at a concentration of 1-5 µg/ml.
This antibody has only been tested in WB against the recombinant fragment used as immunogen. We have no data on the detection of endogenous protein.
Not yet tested in other applications. Optimal dilutions/concentrations should be determined by the end user.
功能Regulatory subunit of the calcium activated potassium KCNMA1 (maxiK) channel. Modulates the calcium sensitivity and gating kinetics of KCNMA1, thereby contributing to KCNMA1 channel diversity. Alters the functional properties of the current expressed by the KCNMA1 channel. Isoform 2, isoform 3 and isoform 4 partially inactivate the current of KCNBMA. Isoform 4 induces a fast and incomplete inactivation of KCNMA1 channel that is detectable only at large depolarizations. In contrast, isoform 1 does not induce detectable inactivation of KCNMA1. Two or more subunits of KCNMB3 are required to block the KCNMA1 tetramer.
组织特异性Isoform 1, isoform 3 and isoform 4 are widely expressed. Isoform 2 is expressed placenta, pancreas, kidney and heart. Isoform 1 and isoform 3 are highly expressed in pancreas and testis.
序列相似性Belongs to the KCNMB (TC 8.A.14.1) family. KCNMB3 subfamily.
结构域Isoform 4 cytoplasmic N-terminal domain participates in the partial inactivation of KCNMA1, possibly by binding to a receptor site. The extracellular domain forms gates to block ion permeation, providing a mechanism by which current can be rapidly diminished upon cellular repolarization.
翻译后修饰N-glycosylated. The extracellular domain contains disulfide bond essential for the gating mechanism.
