TMEM106A has been identified as a key factor to regulate macrophage activation and a tumour suppressor in gastric, renal cancer and non small-cell lung carcinoma (NSCLC) [1,2]. TMEM106B localises to late endosomes and lysosomes, and it is involved in dendrite morphogenesis and maintenance by regulating lysosomal trafficking via its interaction with MAP6 [3]. Its overexpression is associated with familial frontotemporal lobar degeneration [4]. It has also been identified as a protein required for productive SARS-CoV-2 [5]. Structural analysis of LEA-2 domains revealed that they have a long, conserved lipid-binding groove, implying that TMEM106B and its homologues Vac7 and Tag1 from yeast, may all be lipid transfer proteins in the lumen of late endocytic organelles [5].
