Biological background
SSTR5 (protein: T-cell surface glycoprotein CD3 zeta chain) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Cysteine protease required for the cytoplasm to vacuole transport (Cvt) and autophagy. Cleaves the C-terminal amino acid of ATG8 family proteins MAP1LC3, GABARAPL1, GABARAPL2 and GABARAP, to reveal a C-terminal glycine. Exposure of the glycine at the C- terminus is essential for ATG8 proteins conjugation to phosphatidylethanolamine (PE) and insertion to membranes, which is necessary for autophagy. Has also an activity of delipidating enzyme for the PE-conjugated forms. . Reported cellular localization context: Cytoplasm . Tissue expression notes (as provided): Mainly expressed in the skeletal muscle, followed by brain, heart, liver and pancreas. .
Research relevance and current trends
- Research context keywords from the source record include: Cancer,Cardiovascular,Cell Biology,Cell Death,Extracellular Matrix,Invasion/Microenvironment,Metabolism,Metabolism Processes,Pathways and Processes,Proteolysis/Ubiquitin,Proteolytic Enzymes,Signal Transduction.
- Current studies often focus on connecting target abundance/localization to pathway perturbations across models, tissues, and cell states.
- Quantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.
Common research applications
- Western blotting (WB): assess relative target abundance across samples, treatments, or time-points.
- Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.
Workflow ideas (metafield): Validate SSTR5 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect SSTR5 expression by Western blot in cell or tissue lysates, Quantify SSTR5-positive cells by flow cytometry in single-cell suspensions
Notes for experimental interpretation
- Consider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.
- Apparent molecular weight may vary by sample type and processing (observed MW: 42 kDa; calculated MW: 44294 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
