TMEM106B (transmembrane protein 106B) plays an integral role in microglia and oligodendrocyte function (Lok and Kwok 2021). It is of 274 aas with 1 or 2 TMSs. It is involved in several diseases and is linked to cell death (see family description) (Nicholson and Rademakers 2016). It exerts its effects on FTLD-TDP disease risk through alterations in lysosomal pathways, and TMEM106B and C9orf72 may interact in FTLD-TDP pathophysiology (Busch et al. 2016). Loss of TMEM106B exacerbates C9ALS/FTD DPR pathology by disrupting autophagosome maturation (Bauer et al. 2022). The TMEM106B core deposition associates with TDP-43 pathology and is increased in risk SNP carriers for frontotemporal dementia (Marks et al. 2024).

TMEM106C of 250 aas and 2 TMSs. TMEM106C contributes to the malignant characteristics and poor prognosis of hepatocellular carcinoma (HCC) (Duan et al. 2021). TMEM106C is overexpressed in HCC, and its inhibition suppresses the proliferation and metastasis of HCC. Upregulation of TMEM106C correlated with sex, tumor stage, tumor grade and prognosis. Overexpression of TMEM106C was linked to functional networks involving organelle fission and cell cycle signaling pathways (Duan et al. 2021).
