KIBRA (human)

KIBRA a postsynaptic scaffolding protein associated with human memory performance. Interacts via its WW domains with the postsynaptic protein DDN, which plays a role in synaptic plasticity. Expressed in the hypothalamus and cerebellum, and in the hippocampus and cortex, both regions of the brain that are related to memory. Co-localizes with PKCZ in the mouse hippocampus. Binds to synaptopodin, modulating podocyte directional migration. Forms a complex with dynein light chain 1 that is recruited to ER-responsive promoters, and that is required for ER transactivation in breast cancer cells. Binds the minus end-directed microtubule motor dynein. Its amino terminus binds the eight PDZ domain of the polarity protein INADL . Two human isoforms have been described.
