It is mapped to 13q34. This gene encodes the major type IV alpha collagen chain of basement membranes. Like the other members of the type IV collagen gene family, this gene is organized in a head-to-head conformation with another type IV collagen gene so that each gene pair shares a common promoter. COL4A1 binds to alpha-1\/beta-1 integrin and inhibits migration, proliferation, and tube formation by endothelial cells. It is also a potential therapeutic candidate for targeting tumor angiogenesis.\u003c\/p\u003e\n\u003cp\u003eFor curated annotations (gene\/protein naming, domains, isoforms, and pathway links) for COL4A1, consult primary databases such as UniProt, NCBI Gene, and Ensembl.\u003c\/p\u003e\n\n\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\n\u003cul\u003e\n  \n\u003cli\u003eContext-dependent expression studies: researchers often examine COL4A1 abundance and localization across perturbations (genetic, pharmacologic, or environmental) to connect phenotype to molecular changes.\u003c\/li\u003e  \u003cli\u003eReagent reproducibility: there is growing emphasis on antibody specificity checks using orthogonal approaches (e.g., genetic perturbation or independent antibodies) and transparent reporting of clone\/lot information.\u003c\/li\u003e  \u003cli\u003eMulti-modal datasets: antibody-based readouts are increasingly combined with transcriptomics and imaging to relate protein-level measurements to cell-state transitions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCommon research applications\u003c\/h2\u003e\n\u003cul\u003e\n  \n\u003cli\u003eWestern blotting (immunoblot) for relative detection of target protein abundance and apparent molecular weight.\u003c\/li\u003e  \u003cli\u003eImmunohistochemistry for spatial mapping of target expression across tissues and cell types.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhen comparing conditions, interpret changes in signal in the context of sample composition, expected localization, and any known isoform complexity for the target.\u003c\/p\u003e\n\n\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\n\u003cul\u003e\n  \n\u003cli\u003e\n\u003cstrong\u003eIsoforms and PTMs:\u003c\/strong\u003e alternative splicing or post-translational modifications can change epitope accessibility and apparent molecular weight; interpret bands\/signals accordingly.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eCross-reactivity and matrix effects:\u003c\/strong\u003e background binding can vary by sample type, species, and blocking\/detection chemistries; include appropriate negative controls.\u003c\/li\u003e  \u003cli\u003e\n\u003cstrong\u003eControl concepts:\u003c\/strong\u003e where feasible, use genetic perturbation (KO\/KD\/overexpression), orthogonal assays, or independent antibodies to support specificity claims.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAntibody considerations:\u003c\/strong\u003e Polyclonal reagents may recognize multiple epitopes and can increase sensitivity but may show broader binding profiles, while monoclonal clones provide a single-epitope readout that can improve consistency across experiments.
