CARD-CC family
The CARD-CC protein family is defined by an evolutionary conserved CARD and a coiled-coil (CC) domain.[1] Coiled-coils (CC) act as oligomerization domains for many proteins such as structural and motor proteins, and transcription factors. This means that monomers are converted to macromolecular complexes by polymerization.[2] The protein family is ancient and can be found as far back as Cnidaria, but has almost exclusively been studied in humans and mice. Notably, the protein family is absent in insects and nematodes, which makes it impossible to study its function in the most popular invertebrate model organisms (Drosophila and C. elegans). In humans and other jawed vertebrates, the family consists of CARD9 and the three "CARD-containing MAGUK protein" (CARMA)[3] proteins CARD11 (CARMA1), CARD14 (CARMA2) and CARD10 (CARMA3).
Functions
A common theme for all four CARD-CC family proteins in mice and humans is that they recruit BCL10 and the paracaspase MALT1 upon activation, which results in downstream activation of NF-κB transcriptional activity and expression of pro-inflammatory cytokines. The different CARD-CC family members show different expression pattern and gain- or loss of function mutation in the different CARD-CC family proteins cause different phenotypes.
- Function as oligomerization domains for structural and motor proteins, and transcription factors .[2]
- Loss-of-function mutations in CARD9 disrupts lectin receptor signaling like Dectin 1, which causes enhanced susceptibility to fungal infections.[4]
- Strong loss-of-function mutations in CARD11 cause severe defects in lymphocyte function since it is a critical downstream signal mediator in T- and B-cell antigen receptor signaling, which results in severe combined immunodeficiency (SCID).[5]
- Weak (hypomorphic) mutations in CARD11 causes atopic dermatitis disease.[6]
- Gain-of-function mutations in CARD11 can result in B-cell lymphoma.[7][8]
- Gain-of-function mutations in CARD14 results in psoriasis or PRP.[9]
- There are indications that loss-of-function mutations in CARD14 could result in atopic dermatitis due to disrupted immune responses against skin microbes.[10]
- There are no obvious gain- or loss-of-function mutations in CARD10, but it is sometimes over-expressed in certain cancer variants,[11] and there is a SNP in CARD10 associated to glaucoma.[12]
