NCBI Conserved Domains — summary generated by Brevi Assistant
BRCA1, described RING finger healthy protein 53, is a RING finger protein inscribed by BRCA1, a growth suppressor gene that controls all DNA double-strand break repair work paths. BRCA1 consists of an N-terminal C3HC4-type RING-HC finger, and two BRCT repeats at the C-terminus. BRCA1 is often altered in patients with hereditary breast and ovarian cancer. BRCA1, also referred to as RING finger protein 53, is a RING finger healthy protein encoded by lump suppressor gene BRCA1 that controls all DNA double-strand break fixing pathways. The third finger is a customized kind of Zn-finger of 40 to 60 residues that binds 2 atoms of zinc. Nonetheless, not all RING finger-containing healthy proteins present regular RING finger features, and the RING finger family has ended up being many. Src Homology 3 domains are healthy protein interaction domains that bind proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. They have been shown to bind peptide sequences that lack the PxxP theme; instances include the PxxDY theme of Eps8 and the RKxxYxxY series in SKAP55. Ubiquitin is a protein modifier that is associated with different cellular processes including transcriptional guideline, cell cycle control, and DNA repair in eukaryotes. Ubiquitin-like proteins have similar ubiquitin beta-grasp fold and connect to various other proteins in a ubiquitin-like way however with biochemically distinctive duties.

This gene inscribes a 190 kD nuclear phosphoprotein that contributes to maintaining genomic stability, and it also acts as a tumor suppressor. Mutations in this gene are accountable for around 40% of acquired breast cancers and greater than 80% of acquired breast and ovarian cancers. Acquired mutations in BRCA1 and this gene, BRCA2, confer increased lifetime threat of creating breast or ovarian cancer. BRCA2 is considered a tumor suppressor gene, as growths with BRCA2 mutations normally show loss of heterozygosity of the wild-type allele. In response to DNA damages and replication blocks, cell cycle progression is halted via the control of critical cell cycle regulatory authorities. This nuclear healthy protein is a member of the CDS1 subfamily of serine/threonine healthy protein kinases. This gene encodes an estrogen receptor and ligand-activated transcription element. The approved protein includes an N-terminal ligand-independent transactivation domain, a central DNA binding domain, a hinge domain, and a C-terminal ligand-dependent transactivation domain. Telomerase is a ribonucleoprotein polymerase that preserves telomere ends by enhancement of the telomere repeat TTAGGG. Research studies in mouse recommend that telomerase also participates in chromosomal fixing, since de novo synthesis of telomere repeats may occur at double-stranded breaks. This gene inscribes a tumor suppressor protein containing transcriptional activation, DNA binding, and oligomerization domains. Extra isoforms have also been shown to arise from making use of alternating translation initiation codons from the same record versions.
