26617795 TMP21 modulates cell growth in papillary thyroid cancer cells by inducing autophagy, which may be associated with activation of AMPK/mTOR pathway.
23434013 Study demonstrates that NleF binds to the human Tmp21 protein and subsequently disrupts intracellular protein trafficking.

20164256 These results demonstrate that p23/Tmp21 acts as an anchor that distinctively modulates compartmentalization of C1 domain-containing proteins, and it plays an essential role in beta2-chimaerin relocalization.
19710022 the TMP21 transmembrane domain promotes its association with the presenilin complex that results in decreased gamma-cleavage activity
19343178 Observational study and genome-wide association study of gene-disease association. (HuGE Navigator)
19046380 Taken together, these results indicate that the degradation of TMP21, as with the other presenilin-associated gamma-secretase complex members, is mediated by the ubiquitin-proteasome pathway.
18652896 p23 is widely distributed throughout the frontal cortex, hippocampus and cerebellum of control and Alzheimer disease (AD)brains; steady-state p23 levels are reduced in the brains of individuals with AD.
18405662 TMP21 behaves as a regulator of gamma- but not epsilon-cleavages of beta-amyloid precursor protein generated by presenilin-dependent gamma-secretase complex.
