Biological background

Biological context: Inhibitor of PPP1CA. Has over 1000-fold higher inhibitory activity when phosphorylated, creating a molecular switch for regulating the phosphorylation status of PPP1CA substrates and smooth muscle contraction.

Expression and localization notes: cellular localization: Cytoplasm ., tissue context: Isoform 1 is detected in aorta and testis. Isoform 2 is detected in aorta. ..

Common research applications

• Western blotting (WB): Compare N levels across samples and conditions using appropriate loading and biological controls.
• Immunohistochemistry (IHC): Evaluate spatial distribution of N in tissue sections, considering fixation and antigen retrieval effects.
• Flow cytometry: Quantify N-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: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is an enveloped, positive-sense, single-stranded RNA virus that causes coronavirus disease 2019 (COVID-19). Virus particles include the RNA genetic material and structural proteins needed for invasion of host cells. Once inside the cell the infecting RNA is used to encode structural proteins that make up virus particles, nonstructural proteins that virus assembly, transcription, replication and host control and accessory proteins whose function has not been determined.~ The structural proteins of SARS-CoV-2 include the envelope protein (E), spike or surface glycoprotein (S), membrane protein (M) and the nucleocapsid protein (N). The nucleocapsid phosphoprotein is a structural protein that binds to, protects the viral RNA genome and is involved in packaging the RNA into virus particles. The N protein has been suggested as an antiviral drug target.
