Protein KIBRA also known as kidney and brain expressed protein (KIBRA) or WW domain-containing protein 1 (WWC1) is a protein that in humans is encoded by the WWC1 gene.[1][2][3]

A single nucleotide polymorphism (rs17070145) in the gene has been association with human memory performance in one 2006 study.[4] No significant support for association with memory was found in a study with 584 subjects.[5] However it was replicated in a smaller study of the elderly.[6] A subsequent study in two large UK samples indicated that KIBRA is specifically associated with forgetting of non-semantic material.[7]

Studies have also begun to investigate the role of KIBRA in Alzheimer's disease.[8]

Interactions[edit]

KIBRA has at least 10 interaction partners, including synaptopodin, PKCζ and Dendrin, most of which modify synaptic plasticity. For instance, Dendrin is a post-synaptic protein with expression regulated by sleep deprivation.[9] KIBRA has been shown to interact with Protein kinase Mζ.[10]
