The human C22orf41 protein, encoded by the chromosome 22 open reading frame 41 gene, remains poorly characterized, with limited functional data available. Located on 22q13.1, this gene spans approximately 14 kb and is conserved across vertebrates, suggesting evolutionary importance. Bioinformatic analyses predict a 271-amino-acid protein (~30 kDa) with potential α-helical domains but no canonical functional motifs. Expression studies indicate ubiquitous low-level mRNA distribution across tissues, with slightly elevated levels in brain and testes.
Recombinant C22orf41 protein production typically employs bacterial systems (e.g., E. coli) using His-tagged constructs for affinity purification. Despite its unknown physiological role, preliminary evidence links it to cilia-associated processes and Wnt signaling modulation. A 2021 proteomics study identified interactions with microtubule-associated proteins, hinting at cytoskeletal involvement.
Notably, rare C22orf41 missense variants have been reported in intellectual disability cohorts, though pathogenicity remains unconfirmed. Current research focuses on resolving its subcellular localization (predicted cytoplasmic/nuclear) and post-translational modifications. The absence of knockout models in public databases underscores its understudied status, presenting opportunities for novel functional discoveries in basic cell biology and potential connections to neurodevelopmental disorders.
