Biological background

CD5 (protein: T-cell surface glycoprotein CD4) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Component of the microprocessor complex that acts as a RNA- and heme-binding protein that is involved in the initial step of microRNA (miRNA) biogenesis. Component of the microprocessor complex that is required to process primary miRNA transcripts (pri-miRNAs) to release precursor miRNA (pre-miRNA) in the nucleus. Within the microprocessor complex, DGCR8 function as a molecular anchor necessary for the recognition of pri-miRNA at dsRNA-ssRNA junction and s DROSHA to cleave 11 bp away form the junction to release hairpin-shaped pre-miRNAs that are subsequently cut by the cytoplasmic DICER to generate mature miRNAs. The heme-bound DGCR8 dimer binds pri-miRNAs as a cooperative trimer (of dimers) and is active in triggering pri- miRNA cleavage, whereas the heme-free DGCR8 monomer binds pri- miRNAs as a dimer and is much less active. Both double-stranded and single-stranded regions of a pri-miRNA are required for its binding (PubMed:15531877, PubMed:15574589, PubMed:15589161, PubMed:16751099, PubMed:16906129, PubMed:16963499, PubMed:17159994). Specifically recognizes and binds N6- methyladenosine (m6A)-containing pri-miRNAs, a modification required for pri-miRNAs processing (PubMed:25799998). Involved in the silencing of embryonic stem cells self-renewal (By similarity). . Reported cellular localization context: Nucleus . Nucleus, nucleolus . Colocalizes with nucleolin and DROSHA in the nucleolus. Mostly detected in the nucleolus as electron-dense granular patches around the fibrillar center (FC) and granular component (GC). Also detected in the nucleoplasm as small foci adjacent to splicing speckles near the chromatin structure. Localized with DROSHA in GW bodies (GWBs), also known as P-bodies (PubMed:17159994). Tissue expression notes (as provided): Ubiquitously expressed. .

Research relevance and current trends

• Research context keywords from the source record include: Adaptive Immunity,B Cells,Hematopoietic Progenitors,Immunology,Lymphoid,Stem Cells,T Cells,T Lymphocytic Lineage.
• 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.
• Immunohistochemistry (IHC): evaluate spatial distribution of target-positive staining in tissue architecture.
• Immunofluorescence/ICC (IF/ICC): visualize subcellular localization patterns and cell-to-cell heterogeneity.
• Immunoprecipitation (IP): enrich target complexes for downstream immunoblot or interaction analyses.

Workflow ideas (metafield): Validate CD5 antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect CD5 expression by Western blot in cell or tissue lysates, Detect CD5 in FFPE tissue sections by immunohistochemistry, Localize CD5 by immunofluorescence/immunocytochemistry in cultured cells, Enrich CD5 by immunoprecipitation from lysates for downstream analysis

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: 501 kDa; calculated MW: 86045 MW).
• Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
