Biological background
Biological context: May be involved in follicular development. Oocyte-specific growth/differentiation factor that stimulates folliculogenesis and granulosa cell (GC) growth. The mature protein migrates in two distinct mature proteins, P16 (16KDa) and P17 (17KDa). Ovarian physiology and fertility are controlled by endocrine and paracrine signals. These act in a species-dependent manner and determine the ovulation quota in different mammalian species. While humans, and mammals such as the cow or red deer, normally ovulate only one egg per cycle, other mammals such as mouse and pig can ovulate in excess of ten per cycle. The mechanisms that regulate the species-specific differences in the number of follicles that go onto ovulate during each reproductive cycle are poorly understood. According to PubMed:21970812, mRNA expression levels of GDF9 and BMP15 are tightly coregulated within each species and influence species-specific ovulation-rates.
Expression and localization notes: cellular localization: Secreted..
Common research applications
- Western blotting (WB): Compare KPNB1 levels across samples and conditions using appropriate loading and biological controls.
- Immunohistochemistry (IHC): Evaluate spatial distribution of KPNB1 in tissue sections, considering fixation and antigen retrieval effects.
- Immunofluorescence / ICC: Assess subcellular localization patterns and co-localization with compartment markers in cultured cells.
- Flow cytometry: Quantify KPNB1-positive populations in single-cell suspensions with appropriate gating and controls.
- ELISA: Use antibody-based detection formats to assess antigen presence or binding in plate-based assays.
Notes for experimental interpretation
- Account for isoforms, post-translational modifications, and sample-specific processing that can shift apparent molecular weight or epitope accessibility.
- Use positive/negative biological controls where possible (e.g., known-expressing cells/tissues, knockdown/knockout models) and include appropriate secondary-only/isotype controls for imaging workflows.
Additional product notes (from provided fields)
- Background: Importin subunit beta-1 is a protein that in humans is encoded by the KPNB1 gene. Nucleocytoplasmic transport, a signal- and energy-dependent process, takes place through nuclear pore complexes embedded in the nuclear envelope. The import of proteins containing a nuclear localization signal (NLS) requires the NLS import receptor, a heterodimer of importin alpha and beta subunits also known as karyopherins. Importin alpha binds the NLS-containing cargo in the cytoplasm and importin beta docks the complex at the cytoplasmic side of the nuclear pore complex. In the presence of nucleoside triphosphates and the small GTP binding protein Ran, the complex moves into the nuclear pore complex and the importin subunits dissociate. Importin alpha enters the nucleoplasm with its passenger protein and importin beta remains at the pore. Interactions between importin beta and the FG repeats of nucleoporins are essential in translocation through the pore complex. The protein encoded by this gene is a member of the importin beta family. Two transcript variants encoding different isoforms have been found for this gene.
- Cross reactivity: No cross-reactivity with other proteins.
- Cellular localization: Secreted.
