Title: TM9SF4 Is a Crucial Regulator of Inflammation and ER Stress in Inflammatory Bowel Disease.
results uncovered a novel role of TM9SF4 proteins in alleviating endoplasmic reticulum stress and protecting chemoresistant breast cancer cells from apoptotic/necrotic cell death
Title: Knockdown of TM9SF4 boosts ER stress to trigger cell death of chemoresistant breast cancer cells.
Results show that TM9SF4 controls the sorting of TMDs at the ER-Golgi interface. Remarkably, sorting of T-R1 in HCT116 cells was different from that in HEK cells: in HCT116 cells, a substantial fraction of T-R1 was localized to the Golgi complex, and it was relocated to the ER by genetic ablation of TM9SF4.
Title: TM9SF4 levels determine sorting of transmembrane domains in the early secretory pathway.
The TM9SF4 functions to facilitate mTOR inactivation, resulting in an enhanced autophagic flux, which serves to protect cells from apoptotic cell death.
Title: TM9SF4 is a novel factor promoting autophagic flux under amino acid starvation.
TM9SF4 is a direct target of HIF-1alpha, down-regulated in leukemic cells by hypoxia and involved in cell adhesion.
Title: Human TM9SF4 Is a New Gene Down-Regulated by Hypoxia and Involved in Cell Adhesion of Leukemic Cells.
Our study shows for the first time the important role of TM9SF4 in the aberrant constitutive activation of the V-ATPase, and the development of a malignant phenotype.
Title: TM9SF4 is a novel V-ATPase-interacting protein that modulates tumor pH alterations associated with drug resistance and invasiveness of colon cancer cells.
TM9SF4 is a new marker of malignancy, representing a potential new target for anti-tumour strategies with a specific role in tumour cannibalism and in the establishment of a metastatic phenotype.
Title: The human homologue of Dictyostelium discoideum phg1A is expressed by human metastatic melanoma cells.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
