PR domain zinc finger protein 2 is a protein that in humans is encoded by the PRDM2 gene. [5] [6]
This tumor suppressor gene is a member of a nuclear histone/protein methyltransferase superfamily. It encodes a zinc finger protein that can bind to retinoblastoma protein, estrogen receptor, and the TPA-responsive element (MTE) of the heme-oxygenase-1 gene. Although the functions of this protein have not been fully characterized, it may (1) play a role in transcriptional regulation during neuronal differentiation and pathogenesis of retinoblastoma, (2) act as a transcriptional activator of the heme-oxygenase-1 gene, and (3) be a specific effector of estrogen action. Three transcript variants encoding different isoforms have been found for this gene. [6]
PRDM2 has been shown to interact with Estrogen receptor alpha [7] and Retinoblastoma protein. [5]
The Krüppel associated box (KRAB) domain is a category of transcriptional repression domains present in approximately 400 human zinc finger protein-based transcription factors. The KRAB domain typically consists of about 75 amino acid residues, while the minimal repression module is approximately 45 amino acid residues. It is predicted to function through protein-protein interactions via two amphipathic helices. The most prominent interacting protein is called TRIM28 initially visualized as SMP1, cloned as KAP1 and TIF1-beta. Substitutions for the conserved residues abolish repression.
Estrogen receptor alpha (ERα), also known as NR3A1, is one of two main types of estrogen receptor, a nuclear receptor that is activated by the sex hormone estrogen. In humans, ERα is encoded by the gene ESR1.
Retinoblastoma-like protein 2 is a protein that in humans is encoded by the RBL2 gene.

Zinc finger E-box-binding homeobox 1 is a protein that in humans is encoded by the ZEB1 gene.
Tripartite motif-containing protein 25 is a protein that in humans is encoded by the TRIM25 gene.
Zinc finger and BTB domain-containing protein 7A is a protein that in humans is encoded by the ZBTB7A gene.
AT rich interactive domain 4A (RBP1-like), also known as ARID4A, is a protein which in humans is encoded by the ARID4A gene.
Zinc finger protein OZF is a protein that in humans is encoded by the ZNF146 gene.
Zinc finger protein 217, also known as ZNF217, is a protein which in humans is encoded by the ZNF217 gene.
Zinc finger and BTB domain-containing protein 32 is a protein that in humans is encoded by the 1960 bp ZBTB32 gene. The 52 kDa protein is a transcriptional repressor and the gene is expressed in T and B cells upon activation, but also significantly in testis cells. It is a member of the Poxviruses and Zinc-finger (POZ) and Krüppel (POK) family of proteins, and was identified in multiple screens involving either immune cell tumorigenesis or immune cell development.
Protein Jade-3 is a protein that in humans is encoded by the PHF16 gene.
Zinc finger protein 44 is a protein that in humans is encoded by the ZNF44 gene.
Zinc finger protein 7 is a protein that in humans is encoded by the ZNF7 gene.
Peroxisomal proliferator-activated receptor A interacting complex 285, also known as PRIC285, is a human gene.
Zinc finger protein 423 is a protein that in humans is encoded by the ZNF423 gene.
Cip1-interacting zinc finger protein is a protein that in humans is encoded by the CIZ1 gene.
Zinc finger and BTB domain-containing protein 40 is a protein that in humans is encoded by the ZBTB40 gene.
The retinoblastoma protein is a tumor suppressor protein that is dysfunctional in several major cancers. One function of pRb is to prevent excessive cell growth by inhibiting cell cycle progression until a cell is ready to divide. When the cell is ready to divide, pRb is phosphorylated, inactivating it, and the cell cycle is allowed to progress. It is also a recruiter of several chromatin remodeling enzymes such as methylases and acetylases.
PR domain zinc finger protein 12 is a protein that in humans is encoded by the PRDM12 gene. This gene is normally switched on during the development of pain-sensing nerve cells. People with homozygous mutations of the PRDM12 gene experience congenital insensitivity to pain (CIP). PRMD12 is a part of a larger domain that mediate histone methyltransferases. Enzymes target gene promoters in order to control gene expression.
