Biological background
Protein function (datasheet): SOCS family proteins form part of a classical negative feedback system that regulates cytokine signal transduction. CIS is involved in the negative regulation of cytokines that signal through the JAK-STAT5 pathway such as erythropoietin, prolactin and interleukin 3 (IL3) receptor. Inhibits STAT5 trans-activation by suppressing its tyrosine phosphorylation. May be a substrate- recognition component of a SCF-like ECS (Elongin BC-CUL2/5-SOCS- box protein) E3 ubiquitin-protein ligase complex which mediates the ubiquitination and subsequent proteasomal degradation of target proteins (By similarity). .
Scientific background (datasheet): CISH (cytokine inducible SH2-containing protein),also called CIS, CIS-1, G18, SOCS, is an important negative regulator for inflammatory signaling and belongs to the suppressors of cytokine signaling (SOCS) family. CIS family members are known to be cytokine-inducible negative regulators of cytokine signaling. CISH controls interleukin-2 signaling, and variations of CISH with certain SNPs are associated with susceptibility to bacteremia, tuberculosis and malaria. The human CISH gene is mapped to chromosome 3p21.3 by FISH. The mouse gene is tightly linked to the Gnai2 gene on chromosome 9, a region syntenic to human chromosome 3p21. CIS expression was upregulated by lipopolysaccharide (LPS) or Cryptosporidium parvum exposure, and this upregulation involved downregulation of MIR98 and LET7, which relieved MIR98- and LET7-mediated translational repression of CIS. Gain- and loss-of-function studies showed that CIS accelerated degradation of IKBA and enhanced NFKB activation in cholangiocytes in response to LPS stimulation or C parvum exposure.
Cellular localization (datasheet): Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Cytoplasm, cytoskeleton, spindle pole. Localizes on centrosomes in interphase cells and at each spindle pole in mitosis. Associates with both the pericentriolar material (PCM) and centrioles. Colocalized with SIRT2 at centrosome (By similarity). Detected at the neurite hillock in developing neurons. .
Tissue details (datasheet): Expressed in various epithelial tissues. Abundantly expressed in liver and kidney, and to a lesser extent in lung. The tissue distribution of isoforms 1 and 1B is distinct. .
Sequence similarities (datasheet): Contains 1 SH2 domain.
Research relevance and current trends
- Commonly studied in contexts related to Adapters,Cytoplasmic,Developmental Families,Domain Families,Epigenetics and Nuclear Signaling,Signal Transduction,Transcription.
- Supports comparative expression analysis across conditions, genotypes, or treatments when paired with appropriate controls.
- Useful for confirming target presence and subcellular distribution using orthogonal readouts (e.g., microscopy vs. immunoblotting).
Common research applications
- Western blot (WB): Compare relative target abundance and apparent size/isoforms across samples; interpret bands in light of expected MW and potential PTMs.
- ELISA: Measure target abundance in compatible matrices using a standard-curve readout; ensure dilution linearity and appropriate controls.
- Immunohistochemistry (IHC): Assess tissue distribution and cell-type patterns; interpret staining with appropriate negative controls and antigen context.
- Immunofluorescence / ICC: Visualize subcellular localization and co-localization patterns; consider fixation/permeabilization compatibility and controls.
- Flow cytometry: Quantify target-positive populations in single-cell suspensions; pair with viability and isotype/FMO controls conceptually.
Notes for experimental interpretation
- Consider isoforms, post-translational modifications, and processing that can shift apparent molecular weight or localization.
- Cross-reactivity (datasheet): No cross-reactivity with other proteins
- Use appropriate positive and negative controls (e.g., KO/KD, blocking peptide, or isotype controls) to support specificity interpretation.
As a polyclonal antibody, this reagent may recognize multiple epitopes on the target, which can improve detection robustness but may require careful specificity controls.
