Predicted: Bovine
IHC-P: 1:25
Western Blot (WB)
(Western blot analysis of lysates from human placenta tissue and Jurkat cell line (from left to right), using LIMK2 Antibody (C-term). It was diluted at 1:1000 at each lane. A goat anti-rabbit IgG H&L(HRP) at 1:10000 dilution was used as the secondary antibody.)
Background: Displays serine/threonine-specific phosphorylation of myelin basic protein and histone (MBP) in vitro.

NCBI Description
There are approximately 40 known eukaryotic LIM proteins, so named for the LIM domains they contain. LIM domains are highly conserved cysteine-rich structures containing 2 zinc fingers. Although zinc fingers usually function by binding to DNA or RNA, the LIM motif probably mediates protein-protein interactions. LIM kinase-1 and LIM kinase-2 belong to a small subfamily with a unique combination of 2 N-terminal LIM motifs and a C-terminal protein kinase domain. The protein encoded by this gene is phosphorylated and activated by ROCK, a downstream effector of Rho, and the encoded protein, in turn, phosphorylates cofilin, inhibiting its actin-depolymerizing activity. It is thought that this pathway contributes to Rho-induced reorganization of the actin cytoskeleton. At least three transcript variants encoding different isoforms have been found for this gene.

Uniprot Description
LIMK2: a TKL kinase of the LISK family that regulates actin dynamics. Contains two N-terminal LIM motifs. Phosphorylated and activated by PAK1 and ROCK, downstream effectors of Rho. Phosphorylates cofilin, inhibiting its actin-depolymerizing activity. May contributes to Rho-induced reorganization of the actin cytoskeleton. Two alternative splice variants have been identified.
