In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a b ...

Function
This gene encodes a nuclear protein expressed in a variety of tissues. The rat homolog, Rp8, is transiently expressed in immature thymocytes and is thought to be involved in programmed cell death. Expression of the human gene has been shown to be repressed by BCL6, a transcriptional repressor required for lymph node germinal center development, suggesting that BCL6 regulates apoptosis by its effects on PDCD2. This gene is closely linked on chromosome 6 to the gene for TBP, the TATA binding protein. Six transcripts encoding different proteins have been identified.

Host cell factor C1
Host cell factor 1 (HCFC1, HCF1, or HCF-1), also known as VP16-accessory protein, is a protein that in humans is encoded by the ''HCFC1'' gene.

Parkin (ligase)
Parkin is a 465-amino acid residue E3 ubiquitin ligase, a protein that in humans and mice is encoded by the ''PARK2'' gene. Parkin plays a critical role in ubiquitination – the process whereby molecules are covalently labelled with ubiquitin (U ...
