Biological background
Function: This protein is an anticoagulant protein that acts as an in inhibitor of the thromboplastin-specific complex, which is involved in the blood coagulation cascade.
Cellular localization: Cell membrane; Multi-pass membrane protein. Cell junction, gap junction.
Tissue details: Ubiquitously expressed.
Background: Elongation factor Ts, mitochondrial is a protein that in humans is encoded by the TSFM gene. It is an EF-Ts homolog. This gene encodes a mitochondrial translation elongation factor. The encoded protein is an enzyme that catalyzes the exchange of guanine nucleotides on the translation elongation factor Tu during the elongation step of mitchondrial protein translation. Mutations in this gene are associated with combined oxidative phosphorylation deficiency-3 syndrome. Alternate splicing results in multiple transcript variants.
Cross reactivity: No cross-reactivity with other proteins.
Research relevance and current trends
- Quantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.
- Isoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.
- Context-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.
Common research applications
- Western blot (WB): compare relative target abundance and apparent size shifts (e.g., isoforms/PTMs) across conditions.
- Immunohistochemistry (IHC): assess distribution across tissue compartments and compare staining patterns between groups.
- Flow cytometry: quantify target-positive populations and compare shifts after stimulation or differentiation.
Across these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.
Notes for experimental interpretation
- Apparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.
- Species reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.
- Control concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO/KD, peptide competition, or independent assays) to support interpretation.
For antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.
