產(chǎn)品介紹
Apamin
Inhibitor of small conductance Ca2+-activated K+ channels
小電導(dǎo)鈣激活鉀離子通道抑制劑
Apamin is a neurotoxin that was originally isolated from Apis mellifera. Apamin binds to and inhibits the SK channels(small conductance Ca2+-activated K+ channels) in the brain and spinal cord. Apamin inhibits three subtypes of SK channels (KCa2.1, KCa2.2, and KCa2.3) with different affinity. Apamin does not affect KCa3.1 channel activity. Apaminmost likely acts as a pore blocker such as Scyllatoxin or Tamapin, although residues both inside and outside of the pore region of the SK channels participate in apamin binding. The SK channels are present in a wide range of excitable and non-excitable cells, including cells in the central nervous system, intestinal myocytes, endothelial cells, and hepatocytes.
