Biological background
DROSHA (protein: P2X purinoceptor 1) is a commonly studied target in molecular and cellular biology. Functional context (as provided): Ribonuclease III double-stranded (ds) RNA-specific endoribonuclease 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, DROSHA cleaves the 3' and 5' strands of a stem-loop in pri-miRNAs (processing center 11 bp from the dsRNA- ssRNA junction) to release hairpin-shaped pre-miRNAs that are subsequently cut by the cytoplasmic DICER to generate mature miRNAs. Involved also in pre-rRNA processing. Cleaves double- strand RNA and does not cleave single-strand RNA. Involved in the formation of GW bodies. . Reported cellular localization context: Nucleus . Nucleus, nucleolus . A fraction is translocated to the nucleolus during the S phase of the cell cycle. Localized in GW bodies (GWBs), also known as P-bodies. . Tissue expression notes (as provided): Ubiquitous. .
Research relevance and current trends
- Research context keywords from the source record include: 2339,DNA/RNA,Epigenetics and Nuclear Signaling,Nuclear Receptors,Nuclear Signaling Pathways,RNA Processing.
- 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.
- Flow cytometry: quantify target-positive populations and compare shifts in marker distributions.
Workflow ideas (metafield): Validate DROSHA antibody specificity using KO/KD control samples (WB/IF/IHC as appropriate), Detect DROSHA expression by Western blot in cell or tissue lysates, Detect DROSHA in FFPE tissue sections by immunohistochemistry, Localize DROSHA by immunofluorescence/immunocytochemistry in cultured cells, Quantify DROSHA-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: 159 kDa; calculated MW: 159316 MW).
- Control concepts: include appropriate negative controls (e.g., isotype, KO/KD samples) and orthogonal validation when feasible.
