Product Science Overview
Zinc finger proteins are transcription factors that regulate the expression of genes by binding to specific DNA sequences. The ZNHIT3 protein contains a HIT (Histidine Triad) domain, which is involved in protein-protein interactions and is essential for its function. The HIT domain is a conserved motif found in various proteins and is known for its role in nucleotide-binding and hydrolysis.
ZNHIT3 is predicted to enable thyroid hormone receptor binding activity. It is involved in several critical cellular processes, including:
- Box C/D snoRNP assembly: This process is essential for the maturation of small nucleolar RNAs (snoRNAs), which play a role in the chemical modification of other RNAs.
- Maturation of LSU-rRNA: ZNHIT3 is involved in the maturation of large subunit ribosomal RNA (LSU-rRNA) from a tricistronic rRNA transcript, which includes small subunit rRNA (SSU-rRNA), 5.8S rRNA, and LSU-rRNA.
- snoRNA localization: The protein helps in the proper localization of snoRNAs within the cell.
ZNHIT3 is found in both the cytoplasm and the nucleus of cells. Its expression is regulated by various factors, and it is involved in multiple signaling pathways. The protein’s ability to bind to thyroid hormone receptors suggests that it may play a role in thyroid hormone signaling, which is crucial for metabolism, growth, and development.
Mutations or dysregulation of the ZNHIT3 gene have been associated with certain diseases. For example, ZNHIT3 has been implicated in PEHO syndrome (Progressive Encephalopathy with Edema, Hypsarrhythmia, and Optic Atrophy), a rare genetic disorder. Additionally, it is associated with primary lymphedema, a condition characterized by swelling due to the improper functioning of the lymphatic system.
Research on ZNHIT3 and other zinc finger proteins is ongoing, as they are essential for understanding gene regulation and the development of various diseases. Recombinant forms of ZNHIT3, such as human recombinant ZNHIT3, are used in laboratory studies to investigate its function and interactions with other proteins and nucleic acids.
