Function

Transcription factor that acts as a master regulator of lysosomal biogenesis, autophagy, lysosomal exocytosis, lipid catabolism, energy metabolism and immune response (PubMed:21617040, PubMed:22343943, PubMed:22576015, PubMed:22692423, PubMed:25720963, PubMed:30120233, PubMed:31672913, PubMed:32612235, PubMed:32753672, PubMed:35662396, PubMed:36697823, PubMed:36749723, PubMed:37079666). Specifically recognizes and binds E-box sequences (5'-CANNTG-3'); efficient DNA-binding requires dimerization with itself or with another MiT/TFE family member such as TFE3 or MITF (PubMed:1748288, PubMed:19556463, PubMed:29146937). Involved in the cellular response to amino acid availability by acting downstream of MTOR: in the presence of nutrients, TFEB phosphorylation by MTOR promotes its cytosolic retention and subsequent inactivation (PubMed:21617040, PubMed:22343943, PubMed:22576015, PubMed:22692423, PubMed:25720963, PubMed:32612235, PubMed:32753672, PubMed:35662396, PubMed:36697823). Upon starvation or lysosomal stress, inhibition of MTOR induces TFEB dephosphorylation, resulting in nuclear localization and transcription factor activity (PubMed:22343943, PubMed:22576015, PubMed:22692423, PubMed:25720963, PubMed:32612235, PubMed:32753672, PubMed:35662396, PubMed:36697823). Specifically recognizes and binds the CLEAR-box sequence (5'-GTCACGTGAC-3') present in the regulatory region of many lysosomal genes, leading to activate their expression, thereby playing a central role in expression of lysosomal genes (PubMed:19556463, PubMed:22692423). Regulates lysosomal positioning in response to nutrient deprivation by promoting the expression of PIP4P1 (PubMed:29146937). Acts as a positive regulator of autophagy by promoting expression of genes involved in autophagy (PubMed:21617040, PubMed:22576015, PubMed:23434374, PubMed:27278822). In association with TFE3, activates the expression of CD40L in T-cells, thereby playing a role in T-cell-dependent antibody responses in activated CD4(+) T-cells and thymus-dependent humoral immunity (By similarity). Specifically recognizes the gamma-E3 box, a subset of E-boxes, present in the heavy-chain immunoglobulin enhancer (PubMed:2115126). Plays a role in the signal transduction processes required for normal vascularization of the placenta (By similarity). Involved in the immune response to infection by the bacteria S.aureus, S.typhimurium or S.enterica: infection promotes itaconate production, leading to alkylation, resulting in nuclear localization and transcription factor activity (PubMed:35662396). Itaconate-mediated alkylation activates TFEB-dependent lysosomal biogenesis, facilitating the bacteria clearance during the antibacterial innate immune response (PubMed:35662396). In association with ACSS2, promotes the expression of genes involved in lysosome biogenesis and both autophagy upon glucose deprivation (PubMed:28552616).

Notes

ab314921 is a BSA and Azide free antibody supplied in an unconjugated
format and it is suitable for sandwich ELISAs to quantify Human TFEB (phospho S211).
The recommended pair for sandwich ELISA is:

Capture: Anti-TFEB (phospho S211) antibody [EPR27960-64] - BSA and Azide free (Capture) ab314920, Human TFEB (phospho S211) Capture Antibody (unconjugated)

Detector: ab314921, Human TFEB Detector Antibody (unconjugated)

The recommended antibody orientation is based on internal optimization
for ELISAbased assays. Antibody orientation is assay dependent and
needs to be optimized for each assay type. Please note that the
range provided for this antibody is only an estimation based on the
performance of the product using the recommended antibody pair.
Performance of the antibody pair will depend on the specific
characteristics of your assay. We guarantee the product works in
sandwich ELISA, but we do not guarantee the sensitivity or dynamic
range of the antibody in your assay.

Our carrier-free formats are supplied in a buffer free of BSA,
sodium azide and glycerol for higher conjugation efficiency.
The antibodies are provided at an approximate concentration of
1 mg/ml as measured by the protein A280 method. Use our conjugation
kits for antibody conjugates that are ready-to-use in as
little as 20 minutes with <1 minute hands-on-time and 100% antibody
recovery: available for fluorescent dyes, HRP, biotin and gold.
