Biological background

FNDC5 (protein: T-cell surface glycoprotein CD3 zeta chain) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Coactivator of estrogen receptor-mediated transcription and a corepressor of other nuclear hormone receptors and sequence- specific transcription factors. Plays a role in estrogen receptor (ER) genomic activity when present in the nuclear compartment by activating the ER target genes in a hormonal stimulation dependent manner. Can facilitate ER non-genomic signaling via SRC and PI3K interaction in the cytosol. Plays a role in E2-mediated cell cycle progression by interacting with RB1. May have important functional implications in ER/growth factor cross-talk. Interacts with several growth factor signaling components including EGFR and HRS. Involved in nuclear receptor signaling via its interaction with AR and NR3C1. May promote tumorigenesis via its interaction with and modulation of several oncogenes including SRC, PI3K, STAT3 and EGFR. Plays a role in cancer cell metastasis via its ability to modulate E2-mediated cytoskeleton changes and cell migration via its interaction with SRC and PI3K. Functions as the key stabilizing component of the Five Friends of Methylated CHTOP (5FMC) complex; the 5FMC complex is recruited to ZNF148 by methylated CHTOP, leading to desumoylation of ZNF148 and subsequent transactivation of ZNF148 target genes. . Reported cellular localization context: Nucleus, nucleoplasm . Nucleus. Cytoplasm. Mainly found in the nucleoplasm, with low levels detected in the cytoplasm (By similarity). Also found associated with the plasma membrane. Mainly in cytoplasm in a subset of breast tumors. Localization is widely deregulated in endometrial cancers with predominantly cytoplasm localization in high-grade endometrial tumors. . Tissue expression notes (as provided): Widely expressed. .

Research relevance and current trends

• Research context keywords from the source record include: Cell Type Marker,Neuron Marker,Neuroscience,Protein Trafficking,Signal Transduction,Synapse Marker,Vesicle Transport.
• 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.

Workflow ideas (metafield): Validate FNDC5 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect FNDC5 expression by Western blot in cell or tissue lysates, Compare relative FNDC5 levels across experimental conditions (dose/time-course) using antibody-based readouts

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: 23 kDa; calculated MW: 119700 MW).
• Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
