L-Palmitoylcarnitine, a long-chain acylcarnitine and a fatty acid metabolite, accumulates in the sarcolemma and deranges the membrane lipid environment during ischaemia. L-Palmitoylcarnitine inhibits KATP channel activity, without affecting the single channel conductance, through interaction with Kir6.2.

Description

L-Palmitoylcarnitine, a long-chain acylcarnitine and a fatty acid metabolite, accumulates in the sarcolemma and deranges the membrane lipid environment during ischaemia. L-Palmitoylcarnitine inhibits KATP channel activity, without affecting the single channel conductance, through interaction with Kir6.2[1].

IC50 & Target[1]

Kir6.2

 

Human Endogenous Metabolite

 

In Vitro

L-Palmitoylcarnitine (1 µM) inhibits KATP channel activity, without affecting the single channel conductance, through interaction with Kir6.2. L-Palmitoylcarnitine simultaneously enhances the ATP sensitivity of the channel (IC50 fell from 62 to 30 µM)[1].
Modulation of the membrane lipid environment caused by L-Palmitoylcarnitine alters the KATP channel function mainly through the interaction with endogenous PI cascade, especially PIP2[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
