**Background of Human WD Repeat Domain 31 (WDR31) Protein**
WDR31 is a member of the WD40-repeat protein family, characterized by tandem repeats of ~40 amino acids typically forming β-propeller structures that facilitate protein-protein interactions. It plays roles in diverse cellular processes, including signal transduction, cytoskeletal organization, and ciliary function. Although the precise molecular mechanisms of WDR31 remain understudied, emerging evidence links it to ciliogenesis and cilia-related pathways. Cilia are critical for sensory and signaling functions, and defects in ciliary proteins are associated with developmental disorders termed "ciliopathies."
WDR31 localizes to the basal body of cilia and interacts with components of the intraflagellar transport (IFT) system, suggesting a role in ciliary assembly or maintenance. Mutations in WDR31 have been implicated in syndromes such as Bardet-Biedl syndrome (BBS) and Joubert syndrome, which manifest with retinal degeneration, kidney abnormalities, and neurological deficits. Additionally, WDR31 may regulate the Hedgehog signaling pathway, a key developmental cascade dependent on functional cilia.
Despite these insights, WDR31's full functional repertoire and regulatory networks remain unclear. Studies using model organisms and gene-editing tools continue to explore its contributions to cellular dynamics and disease pathogenesis, highlighting its potential as a therapeutic target for ciliopathies. Further research is needed to unravel its exact biochemical interactions and tissue-specific roles.
