CARD Tricks: Controlling the Interactions of CARD6 with RICK and Microtubules
Bibliographic record
Abstract
In recent years, a number of proteins have been identified that contain a homotypic interaction motif called the caspase recruitment domain (CARD). Most proteins containing a CARD are involved in pathways regulating apoptosis or adaptive or innate immunity. Examples of prominent CARD proteins are caspase-9 and Apaf1, which are involved in the intrinsic death pathway; BCL10 and CARD11, which mediate antigen receptor-induced NF-kappaB activation; and receptor-interacting protein (RIP)-like interacting caspase-like apoptosis regulatory protein kinase (RICK) and the nucleotide-binding oligomerization domain (NOD) proteins, which induce NF-kappaB activation in response to intracellular bacterial peptidoglycan. The most recently discovered pathway involving CARD proteins senses virally-derived double-stranded (ds) RNA and initiates a host defense signaling program. CARD6 is a CARD-containing protein with a domain structure not shared by any other CARD protein. Although the CARD6 cDNA was deposited in GenBank five years ago, the physiological function of full-length CARD6 has yet to be reported. Here we review our initial characterization of CARD6 and discuss the functional implications of various conserved modules found in the CARD6 protein sequence. We conclude that CARD6 is structurally and potentially functionally related to the superfamily of interferon (IFN)-inducible GTPases, a growing family of host defense proteins that confer cell-autonomous immunity.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
