that in humans is encoded by the ''BCL10''
gene
In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity. The molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protei ...

BCL2
Bcl-2, encoded in humans by the ''BCL2'' gene, is the founding member of the apoptosis regulator proteins, Bcl-2 family, Bcl-2 family of regulator proteins. BCL2 blocks programmed cell death (apoptosis) while other BCL2 family members can eithe ...

BCL3, BCL5,
BCL6
Bcl-6 (B-cell lymphoma 6) is a protein that in humans is encoded by the ''BCL6'' gene. BCL6 is a master transcription factor for regulation of T follicular helper cells (TFH cells) proliferation. BCL6 has three evolutionary conserved structural d ...

BCL9
B-cell CLL/lymphoma 9 protein is a protein that in humans is encoded by the ''BCL9'' gene.
Function
BCL9, together with its paralogue gene BCL9L (BCL9 like or BCL9.2), have been extensively studied for their role as transcriptional beta-caten ...

lymphoma
Lymphoma is a group of blood and lymph tumors that develop from lymphocytes (a type of white blood cell). The name typically refers to just the cancerous versions rather than all such tumours. Signs and symptoms may include enlarged lymph node ...

Function
Bcl10 was identified by its
translocation in a case of
mucosa-associated lymphoid tissue (MALT) lymphoma. The protein encoded by this gene contains a
caspase recruitment domain (CARD), and has been shown to activate
NF-κB
Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) is a family of transcription factor protein complexes that controls transcription (genetics), transcription of DNA, cytokine production and cell survival. NF-κB is found i ...
. This protein is reported to interact with other
CARD and coiled coil domain containing proteins including
CARD9,
-10,
-11 and
-14, which are thought to function as upstream regulators in NF-κB signaling. This protein is found to form a complex with the
paracaspase MALT1, a protein encoded by another gene known to be translocated in MALT lymphoma. MALT1 and Bcl10 thought to synergize in the activation of NF-κB, and the deregulation of either of them may contribute to the same pathogenetic process that leads to the malignancy.
Bcl10 is evolutionary conserved since
cnidaria
Cnidaria ( ) is a phylum under kingdom Animalia containing over 11,000 species of aquatic invertebrates found both in fresh water, freshwater and marine environments (predominantly the latter), including jellyfish, hydroid (zoology), hydroids, ...
and has been shown to be functionally conserved all the way back to
zebrafish
The zebrafish (''Danio rerio'') is a species of freshwater ray-finned fish belonging to the family Danionidae of the order Cypriniformes. Native to South Asia, it is a popular aquarium fish, frequently sold under the trade name zebra danio (an ...

Notably, just like the upstream
CARD-CC family
The CARD-CC Protein superfamily, protein family is defined by an evolutionary conserved "caspase activation and recruitment domain" (CARD domain, CARD) and a Coiled coil, coiled-coil (CC) domain. Coiled-coils (CC) act as oligomerization domains for ...
