Summaries for LIMK2 Gene

Entrez Gene Summary for LIMK2 Gene

  • 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.

GeneCards Summary for LIMK2 Gene

LIMK2 (LIM Domain Kinase 2) is a Protein Coding gene. Among its related pathways are EPHA forward signaling and Semaphorin interactions. GO annotations related to this gene include transferase activity, transferring phosphorus-containing groups and protein tyrosine kinase activity. An important paralog of this gene is LIMK1.

UniProtKB/Swiss-Prot for LIMK2 Gene

  • Displays serine/threonine-specific phosphorylation of myelin basic protein and histone (MBP) in vitro.

Tocris Summary for LIMK2 Gene

  • LIM kinases (LIMKs), EC, are dual specificity kinases (serine/threonine and tyrosine), which phosphorylate and inactivate cofilin (a key regulator of actin cytoskeleton dynamics). There are two isoforms of LIMK: LIMK1 and LIMK2.
