Anti-CKIP1 PLEKHO1 Antibody

CKIP1 was identified through a yeast-two hybrid screening as a protein that would interact with only one of the two catalytic subunits of the casein kinase 2 complex. CKIP1 is a pleckstrin homology domain-containing protein localized within the nucleus and at the plasma membrane that interacts with CK2alpha but not CK2alpha', and is thought to play a role in targeting CK2alpha to a particular cellular location. CKIP1 has been implicated in muscle differentiation and the regulation of cell morphology and actin cytoskeleton. CKIP1 can also interact with other proteins such as ATM, an upstream kinase of p53, and recruit the nuclear ATM to the plasma membrane, suggesting CKIP1 may regulate ATM function through re-localizing ATM. CKIP1 can also form a complex with the kinase AKT, leading to a down-regulation of PI3K/AKT signaling and suppression of tumor growth in vivo.

CKIP1 antibody was raised against an 18 amino acid synthetic peptide from near the carboxy terminus of human CKIP1. The immunogen is located within the last 50 amino acids of CKIP1.

Abundantly expressed in skeletal muscle and heart, moderately in kidney, liver, brain and placenta and sparingly in the pancreas and lung. Easily detectable in cell lines such as MOLT-4, HEK293 and Jurkat.

Plays a role in the regulation of the actin cytoskeleton through its interactions with actin capping protein (CP) . May function to target CK2 to the plasma membrane thereby serving as an adapter to facilitate the phosphorylation of CP by protein kinase 2 (CK2) . Appears to target ATM to the plasma membrane. Appears to also inhibit tumor cell growth by inhibiting AKT- mediated cell-survival. Also implicated in PI3K-regulated muscle differentiation, the regulation of AP-1 activity (plasma membrane bound AP-1 regulator that translocates to the nucleus) and the promotion of apoptosis induced by tumor necrosis factor TNF. When bound to PKB, it inhibits it probably by decreasing PKB level of phosphorylation.

CKIP1 antibody can be stored at 4°C for three months and -20°C, stable for up to one year. Avoid repeated freeze-thaw cycles. Antibodies should not be exposed to prolonged high temperatures.
