TABLE 1.Examples of p53-interacting Proteins p53 domain involved in Selected p53-interacting protein Method interaction references Activating Transcription Factor 3 (ATF3) GST pull-down,co-IP FL 1 TABLE 1.Examples of p53-interacting Proteins p53 domain involved in Selected p53-interacting protein Method interaction references Activating Transcription Factor 3 (ATF3) GST pull-down,co-IP FL 1 On activation, p53 initiates two major responses: inhibition of proliferation (via cell-cycle arrest, quiescence, senescence, and differentiation) and induction of apoptosis. Importantly, these responses are cell-type and tumor-type-specific. The analysis of mutant p53 alleles has established a gain-of-function role for p53 mutants in metastasis. Based on p53’s critical role in carcino-genesis, scientists have developed multiple effective strategies for treating cancer by enhancing function of wild-type p53 or increasing p53 stability. This review will focus on (i) discussing of the relationship between p53 structure and function, (ii) p53 muta-tions, and (iii) recent strategies for ... enhancing function of wild-type p53 or increasing p53 stability. This review will focus on (i) discussing of the relationship between p53 structure and function, (ii) p53 muta-tions, and (iii) recent strategies for improving the efficacy of cancer treatment by therapeutic manipulation of p53. Journal of Cancer Molecules 2(4): 141-153, 2006 ... Mar 19, 2012 · Hank explains the extremely complex series of reactions whereby plants feed themselves on sunlight, carbon dioxide and water, and also create some by products we're pretty fond of as well.

N-terminally truncated N isoforms possess unique N-terminal sequences. Alpha isoforms of p63 and p73 possess a C-terminal SAM domain followed by a transactivational inhibitory domain (TID). Other isoforms of p53, p63 and p73 are not shown. * Structure and expression of p53 family members. (a) Structure of p53, p63 and p73 transcription units.

The ER structure is described in terms of smooth peripheral tubules and rough ER sheets. The family of proteins responsible for maintaining the sheet or tubule architecture include the cytoskeleton-linking membrane protein 63 (CLIMP-63) and reticulon (RTN), respectively.

However, mutants with more extensive structural changes in the DNA binding core domain may be refractory to reactivation to the wild-type p53 phenotype. Therefore, understanding the structure and functions of oncogenic p53 mutants may lead to more potent reactivation modalities or to the ability to eliminate mutant p53 gain of function. Even 30 years after its discovery, the tumor suppressor protein p53 is still somewhat of an enigma. p53's intimate and multifaceted role in the cell cycle is mirrored in its equally complex structural biology that is being unraveled only slowly. Here, we discuss key structural aspects of p53 function and its inactivation by oncogenic mutations. review on function Natural beta-sheet proteins use negative design to avoid edge-to-edge aggregation. X-RAY CRYSTALLOGRAPHY (2.0 ANGSTROMS) OF 204-210 Acts as a CD40 functional homolog to prevent apoptosis of infected B-lymphocytes and drive their proliferation.
1997 Embo J 16 21 6548-58 This structure is refered to as 'form I' in Beernink (2001). The experimental sequence did not contain the N-terminal residues 1-35. For forms I, II and III of this protein referenced in Beernick (2001) , there is relatively high thermal motion in the areas of residues 100-110, 145, 200 and 270. FEBS 2004 Structure and function of DNA helicases (Eur. J. Biochem. 271) 1853 The crystal structure of full-length eIF-4A from yeast has helicases, which bind both ssDNA and dsDNA. There are been reported  to be a dumbbell structure consisting of two popular models for a general mechanism for heli- two compact domains connected by an ... 2.6. Structure-based selection of novel spiro-oxindole derivatives and testing in vitro. These structure-function studies suggested to us that maximizing van der Waals interactions between the hydrophobic groups of the inhibitors and MDM2 residues would allow us to develop more potent spiro-oxindole inhibitors of the p53-MDM2 interaction.
