KLHDC8B
Developmental stage
Transcribed predominantly during S phase, translated exclusively during mitosis and cytokinesis and rapidly degraded after cell division.
Function
Involved in pinching off the separated nuclei at the cleavage furrow and in cytokinesis (PubMed:20107318). Required for mitotic integrity and maintenance of chromosomal stability. Protects cells against mitotic errors, centrosomal amplification, micronucleus formation and aneuploidy. Plays a key role of midbody function involving abscission of the daughter cells during cytokinesis and appropriate chromosomal and nuclear segregation into the daughter cells (PubMed:22988245, PubMed:23713010).
Involvement in disease
Lymphoma, Hodgkin, classic
CHL
A malignant disease characterized by progressive enlargement of the lymph nodes, spleen and general lymphoid tissue, and the presence of large, usually multinucleate, cells (Reed-Sternberg cells). Reed-Sternberg cells compose only 1-2% of the total tumor cell mass. The remainder is composed of a variety of reactive, mixed inflammatory cells consisting of lymphocytes, plasma cells, neutrophils, eosinophils and histiocytes.
None
Disease susceptibility is associated with variants affecting the gene represented in this entry. A variant in the 5'-UTR of KLHDC8B, responsible for decreasing its expression, is associated with classic Hodgkin lymphoma and segregates with the disease in some families (PubMed:19706467).
A chromosomal aberration disrupting KLHDC8B has been found in a family with the nodular sclerosis type of Hodgkin lymphoma. Translocation t(2,3)(q11.2;p21.31).
Cellular localization
- Cytoplasm
- Midbody
- In mitotic cells, concentrates in the midbody of the cytoplasmic bridge linking daughter cells as they are about to separate during cytokinesis.
