SET (Suppressor of variegation, Enhancer of Zeste, Trithorax) and MYND (Myeloid-Nervy-DEAF1) domain-containing proteins (SMYD) have been found to methylate a variety of histone and non-histone targets which contribute to their various roles in cell regulation including chromatin remodeling, transcription, signal transduction, and cell cycle control. During(More)
Methylation of estrogen receptor α by the histone lysine methyltransferase SMYD2 regulates ERα chromatin recruitment and its target gene expression. This protocol describes SMYD2 purification and crystallization of SMYD2 in complex with an ERα peptide. Recombinant SMYD2 is overexpressed in Escherichia coli cells. After release from the cells by French(More)
In the past decade, the SMYD protein family has gradually become a center of research, thanking for its essential role in heart and muscle development and cancer development. However, because of such a role, the research scope for the SMYD protein family has been fairly stereotyped, its focus largely restricted to muscle and cancer. Initial studies of SMYD1(More)
SMYD proteins are an exciting field of study as they are linked to many types of cancer-related pathways. Cardiac and skeletal muscle development and function also depend on SMYD proteins opening a possible avenue for cardiac-related treatment. Previous crystal structure studies have revealed that this special class of protein lysine methyltransferases have(More)
The CXC chemokine receptor 2 (CXCR2) is a G protein coupled receptor mediating interleukin-8 chemotactic signaling and plays an important role in neutrophil mobility and tumor migration. However, efficient CXCR2 signaling requires PDZ domain-mediated scaffolding of signaling complexes at the plasma membrane and functional coupling of the signaling to(More)
Cystic Fibrosis (CF) is a serious genetic condition caused by CF transmembrane conductance regulator (CFTR) mutation. CF patients have shortened lifespan due to airway obstruction, infection, and end-stage lung failure. However, recent development in CF therapy suggests a brighter future for CF patients. Targeting specific CFTR mutations aims to potentiate(More)
Zika virus (ZIKV) is a flavivirus spread by daytime-active Aedes spp. mosquitoes such as A. aegypti and A. albopictus. Previously thought to be a mild infection, the latest ZIKV outbreak in the Americas is causally associated with more severe symptoms as well as severe birth defects, such as microcephaly. Currently no vaccine or antiviral exists. However,(More)
PDZ domains play an essential role in a number of cellular processes by facilitating protein scaffolding and assembly of protein complexes. These domains consist of 80 to 90 amino acids and are found to recognize short C-terminal sequences of target proteins. Protein complex formation between PDZ target molecules can lead to a number of signaling and(More)
SMYD3 plays a key role in cancer cell viability, adhesion, migration and invasion. SMYD3 promotes formation of inducible regulatory T cells and is involved in reducing autoimmunity. However, the nearly "closed" substrate-binding site and poor in vitro H3K4 methyltransferase activity have obscured further understanding of this oncogenically related protein.(More)
