NDP52 (CALCOCO2) is a selective autophagy receptor gene located on chromosome 21q22.12. The gene encodes a 452 amino acid protein that functions as a critical mediator of selective autophagy. Originally identified as a coactivator for transcription factors, NDP52 has emerged as a key player in innate immunity and selective mitophagy. The gene consists of 11 exons and is expressed in various tissues with particularly high expression in immune cells and neurons.
The CALCOCO2 gene spans approximately 35 kb and includes:
NDP52 produces multiple mRNA isoforms:
