Description: Regulation of neuronal structural plasticity has been found to be important for learning and memory. LIMK1 is an important regulator of postsynaptic structural morphology. In addition, LIMK1 has been found to regulate CREB, which is an important and well studied transcription factor that facilitates the changes from short-term memory to long-term memory. In light of this, I have shown that LIMK1 exists in an immunocomplex with CREB in mature hippocampal neurons. Moreover, mice deficient in LIMK1 were shown to be deficient in late long-term potentiation (L-LTP) induced by high frequency stimulation and L-LTP induced by strong theta burst stimulation, suggestive of a role for LIMK1 in L-LTP and long-term synaptic plasticity. Important regulators of LIMK1 and downstream targets of the RhoGTPases were to be important in long-term memory.
