Target
C11orf52
Molecular classification
Other (Uncharacterized protein; not classified as receptor, enzyme, transporter, ion channel, transcription factor, or histone-modifying enzyme)
01

Overview

Chromosome 11 open reading frame 52 (C11orf52) encodes a small, uncharacterized nuclear protein of 123 amino acids, mapped to chromosome 11q23.1, and highly expressed in several tissues including thyroid, thalamus, pituitary, and placenta[1]. Despite being annotated as a protein-coding gene, its molecular function remains unclear; recent studies reveal its interaction with proteins involved in cell–cell adhesion (especially desmosomal components) and tyrosine signaling, suggesting roles in cellular signaling and structural organization. C11orf52 is also linked to environmental epigenetic regulation, with site-specific DNA methylation patterns in response to exposures like maternal smoking or bisphenol A. While evidence points towards involvement in cancer (particularly lung cancer) and its relevancy as a biomarker for environmental impacts, there are no drugs or targeted therapies for C11orf52, and it is not categorized as a classic druggable target such as a receptor, enzyme, or transporter[1][2][4].
