C1qa encodes the A chain of C1q, ortholog of human C1QA, contributing one of the three collagen-like stalks and globular gC1q heads that assemble with C1QB and C1QC into the hexameric bouquet recognizing IgG and IgM Fc, pentraxins, and exposed phosphatidylserine on apoptotic cells and synapses. Head engagement induces a conformational change in the collagenous arms that activates the associated C1r2C1s2 tetramer, cleaving C4 and C2 to build the classical pathway C3 convertase, while C1q deposited on synapses licenses CR3-dependent microglial pruning and drives complement-mediated synapse loss in neurodegeneration models. Critically, the three chains are not redundant: loss of C1qa destabilizes the entire molecule, producing functional C1q deficiency with impaired apoptotic clearance and lupus-like autoimmunity. Conditional deletion distinguishes microglial from hepatic and macrophage sources, and humanization is worth the effort only when an anti-C1q antibody or classical pathway inhibitor with human-restricted binding is the endpoint.
ingenious targeting laboratory offers 2 distinct C1qa (C1QA) catalog mouse models, featuring conditional knockout and standard knockout. Researchers can order pre-developed catalog lines or request a custom mouse model, including humanized, knockin, and transgenic variations with verified germline transmission.

Order catalog modelA C1qa knockout mouse has the C1qa gene permanently inactivated, enabling loss of function studies. A C1qa conditional knockout (floxed) mouse carries loxP sites flanking a critical exon of C1qa, allowing Cre recombinase dependent deletion in specific tissues or at specific timepoints.
