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 NRXN3 levels across samples and conditions using appropriate loading and biological controls.
• Immunohistochemistry (IHC): Evaluate spatial distribution of NRXN3 in tissue sections, considering fixation and antigen retrieval effects.
• Flow cytometry: Quantify NRXN3-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: Neurexin-3-alpha is a protein that in humans is encoded by the NRXN3 gene. This gene encodes a member of a family of proteins that function in the nervous system as receptors and cell adhesion molecules. Extensive alternative splicing and the use of alternative promoters results in multiple transcript variants and protein isoforms for this gene, but the full-length nature of many of these variants has not been determined. Transcripts that initiate from an upstream promoter encode alpha isoforms, which contain epidermal growth factor-like (EGF-like) sequences and laminin G domains. Transcripts initiating from the downstream promoter encode beta isoforms, which lack EGF-like sequences. Genetic variation at this locus has been associated with a range of behavioral phenotypes, including alcohol dependence and autism spectrum disorder.
• Cross reactivity: No cross-reactivity with other proteins
