TMEM176 proteins are an ion channel expressed in immune cells and certain types of cancer. The transmembrane proteins TMEM176A and 176B belong to the CD20/Fc-µRI² and membrane-spanning 4A (MS4A) family of proteins. Human TMEM176B (also known as LR8) was first discovered in human lung fibroblasts, and was recently associated in human small cell lung carcinoma . Similar to TMEM176A, the lev…
