COP9 Constitutive Photomorphogenic Homolog Subunit 5
COP9 constitutive photomorphogenic homolog subunit 5 (Arabidopsis), also known as COPS5 or Csn5, is a gene conserved from humans to Saccharomyces cerevisiae. Function The protein encoded by this gene is one of the eight subunits of COP9 signalosome, a highly conserved protein complex that functions as an important regulator in multiple signaling pathways. The structure and function of COP9 signalosome is similar to that of the 19S regulatory particle of 26S proteasome. COP9 signalosome has been shown to interact with SCF-type E3 ubiquitin ligases and act as a positive regulator of E3 ubiquitin ligases. This protein is reported to be involved in the degradation of cyclin-dependent kinase inhibitor CDKN1B/p27Kip1. It is also known to be a coactivator that increases the specificity of JUN/AP1 transcription factors. Interactions COP9 constitutive photomorphogenic homolog subunit 5 has been shown to interact with Macrophage migration inhibitory factor, GFER, BCL3, Ubiquitin ...

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: protein-coding genes and non-coding genes. During gene expression (the synthesis of Gene product, RNA or protein from a gene), DNA is first transcription (biology), copied into RNA. RNA can be non-coding RNA, directly functional or be the intermediate protein biosynthesis, template for the synthesis of a protein. The transmission of genes to an organism's offspring, is the basis of the inheritance of phenotypic traits from one generation to the next. These genes make up different DNA sequences, together called a genotype, that is specific to every given individual, within the gene pool of the population (biology), population of a given species. The genotype, along with environmental and developmental factors, ultimately determines the phenotype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S100A7
S100 calcium-binding protein A7 (S100A7), also known as psoriasin, is a protein that in humans is encoded by the ''S100A7'' gene. Function S100A7 is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein differs from the other S100 proteins of known structure in its lack of calcium binding ability in one EF-hand at the N-terminus. The protein functions as a prominent antimicrobial peptide mainly against ''E. coli''. S100A7 also displays antimicrobial properties. It is secreted by epithelial cells of the skin and is a key antimicrobial protein against ''Escherichia coli'' by disrupting their cell membranes. This is the reason that in countries wi ...

C-jun
Transcription factor Jun is a protein that in humans is encoded by the ''JUN'' gene. c-Jun, in combination with protein c-Fos, forms the AP-1 early response transcription factor. It was first identified as the Fos-binding protein p39 and only later rediscovered as the product of the JUN gene. c-jun was the first oncogenic transcription factor discovered. The proto-oncogene c-Jun is the cellular homolog of the viral oncoprotein v-jun (). The viral homolog v-jun was discovered in avian sarcoma virus 17 and was named for ''ju-nana'', the Japanese word for 17. The human JUN encodes a protein that is highly similar to the viral protein, which interacts directly with specific target DNA sequences to regulate gene expression. This gene is intronless and is mapped to 1p32-p31, a chromosomal region involved in both translocations and deletions in human malignancies. Function Regulation Both Jun and its dimerization partners in AP-1 formation are subject to regulation by diverse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ubiquitin Carboxy-terminal Hydrolase L1
Ubiquitin carboxy-terminal hydrolase L1 (, ''ubiquitin C-terminal hydrolase'', ''UCH-L1'') is a deubiquitinating enzyme. Function UCH-L1 is a member of a gene family whose products hydrolyze small C-terminal adducts of ubiquitin to generate the ubiquitin monomer. Expression of UCH-L1 is highly specific to neurons and to cells of the diffuse neuroendocrine system and their tumors. It is abundantly present in all neurons (accounts for 1-2% of total brain protein), expressed specifically in neurons and testis/ovary. The catalytic triad of UCH-L1 contains a cysteine at position 90, an aspartate at position 176, and a histidine at position 161 that are responsible for its hydrolase activity. Relevance to neurodegenerative disorders A point mutation (I93M) in the gene encoding this protein is implicated as the cause of Parkinson's disease in one German family, although this finding is controversial, as no other Parkinson's disease patients with this mutation have been found.

BCL3
B-cell lymphoma 3-encoded protein is a protein that in humans is encoded by the ''BCL3'' gene. This gene is a proto-oncogene candidate. It is identified by its translocation into the immunoglobulin alpha- locus in some cases of B-cell leukemia. The protein encoded by this gene contains seven ankyrin repeats, which are most closely related to those found in I kappa B proteins. This protein functions as a transcriptional coactivator that activates through its association with NF-kappa B homodimers. The expression of this gene can be induced by NF-kappa B, which forms a part of the autoregulatory loop that controls the nuclear residence of p50 NF-kappa B. Like BCL2, BCL5, BCL6, BCL7A, BCL9, and BCL10, it has clinical significance in lymphoma. Interactions BCL3 has been shown to interact with: * BARD1, * C-Fos, * C-jun, * C22orf25, * COPS5, * EP300, * HTATIP, * NFKB1, * NFKB2, * PIR, and * NR2B1.
