Transmembrane protein 120A (TMEM-120A/TACAN) coordinates with PIEZO channel during Caenorhabditis elegans reproductive regulation.

ABSTRACT: Membrane protein TMEM120A (also known as TACAN) was presumed to be both a mechanically activated molecule and a lipid-modifying enzyme. TMEM120A has been identified as a negative regulator of the essential excitatory mechanosensitive protein PIEZO2. However, the extent to which TMEM120A mediates PIEZO2's activity during physiological processes remains largely unknown. In this study, we used the Caenorhabditis elegans reproductive tract to explore the functional contribution of tmem-120, the sole TMEM120A/B ortholog, and its genetic interaction with pezo-1 in vivo. tmem-120 was expressed throughout the C. elegans development, particularly in the germline, embryos, and spermatheca. A tmem-120 mutant with a full-length deletion (tmem-120Δ) displayed deformed germline, maternal sterility, and
