Essential component of a neuregulin-receptor complex, although neuregulins do not interact with it alone. GP30 is a potential ligand for this receptor. Regulates outgrowth and stabilization of peripheral microtubules (MTs). Upon ERBB2 activation, the MEMO1-RHOA-DIAPH1 signaling pathway elicits the phosphorylation and thus the inhibition of GSK3B at cell membrane. This prevents the phosphorylation of APC and CLASP2, allowing its association with the cell membrane. In turn, membrane-bound APC allows the localization of MACF1 to the cell membrane, which is required for microtubule capture and stabilization.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCellular localization:\u003c\/strong\u003e Isoform 1: Cell membrane; Single-pass type I membrane protein.

The human FOXP3 genes contain 11 coding exons. Exon-intron boundaries are identical across the coding regions of the mouse and human genes. By genomic sequence analysis, the FOXP3 gene maps to the p arm of the X chromosome(specifically, Xp11.23). A member of the FOX protein family, FOXP3 appears to function as a master regulator in the development and function of regulatory T cells. While the precise control mechanism has not yet been established, FOX proteins belong to the forkhead\/winged-helix family of transcriptional regulators and are presumed to exert control via similar DNA binding interactions during transcription.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCross reactivity:\u003c\/strong\u003e No cross-reactivity with other proteins\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eQuantitative and spatial profiling: expression patterns are increasingly studied across cell states using multiplex imaging and omics-informed validation.\u003c\/li\u003e \u003cli\u003eIsoforms and post-translational modifications: researchers often evaluate how isoform composition and PTMs can shift apparent molecular weight or localization.\u003c\/li\u003e \u003cli\u003eContext-aware interpretation: comparative studies commonly include perturbations (stimulation, inhibition, genetic models) to relate target changes to pathway behavior.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blot (WB):\u003c\/strong\u003e compare relative target abundance and apparent size shifts (e.g., isoforms\/PTMs) across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e assess distribution across tissue compartments and compare staining patterns between groups.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and compare shifts after stimulation or differentiation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAcross these uses, researchers typically interpret changes in signal as relative differences between matched sample groups, considering sample preparation and biological context.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eApparent molecular weight can vary due to isoforms, proteolysis, glycosylation, phosphorylation, and sample preparation differences.\u003c\/li\u003e \u003cli\u003eSpecies reactivity and epitope conservation can influence observed signal patterns, especially in cross-species studies.\u003c\/li\u003e \u003cli\u003eControl concepts: include appropriate negative controls (e.g., isotype controls where relevant) and, when feasible, genetic or orthogonal controls (KO\/KD, peptide competition, or independent assays) to support interpretation.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eFor antibody reagents, monoclonal antibodies are often chosen for epitope consistency across lots, while polyclonals may recognize multiple epitopes and can show different background characteristics depending on context.\u003c\/p\u003e \u003c!-- Sources (internal): -
