Scientists have mapped the structure of a protein complex believed to influence cancer cell transformation, enabling potential development of unique cancer-fighting drugs. The Cdc42/GDI complex is a key regulator in both normal and cancerous cells.
Researchers have identified a gene called Mre11 as a critical component of the regulatory network that cells activate in response to DNA damage. This discovery explains how mutations in Mre11 can cause ataxia-telangiectasia, a genetic disorder characterized by progressive nerve and muscle loss and increased susceptibility to cancer.
Scientists have produced the first three-dimensional images of the protein complex that initiates DNA transcription, revealing critical components and their interactions. The research provides insights into how transcriptional factors work together to regulate gene expression.
A team of researchers has produced high-resolution images of a complete ribosome complex using the Advanced Light Source (ALS), revealing more about its structure than previous observations. The new crystallographic images provide insights into how transfer RNA interacts with the ribosome and the molecular mechanisms of protein synthesis.
The discovery of Complex II's structure is crucial for understanding the energy production system in cells and may lead to therapies correcting defects. This breakthrough increases scientists' knowledge of fundamental processes and their role in diseases like diabetes and Alzheimer's.
Scientists have confirmed that a protein complex, when defective, causes limb girdle muscular dystrophy. Researchers developed a cell culture system to mimic the defect and found that complete assembly of the sarcoglycan complex is dependent on simultaneous synthesis of all four sarcoglycans.
Scientists have deciphered the molecular structure of neurotransmitter release machinery, revealing how proteins SNAREs propel neurotransmitters into synapses. This breakthrough may lead to improved treatments for brain disorders and shed light on processes like learning and memory.
Researchers have determined the complete crystal structure of cytochrome bc1, a crucial protein complex in the mitochondrial respiratory chain. This breakthrough has provided detailed images of the complex at an unprecedented resolution of 3 angstroms, shedding light on its role in energy production for living cells.
Researchers found that an enzyme called kinase IV is regulated by another enzyme called phosphatase 2A, which attaches to it and quickly shuts it down. This discovery provides insight into how cells control their activities and offers potential for developing targeted drugs to kill cancer cells or bacteria.
Researchers at Rutgers University are developing metalloprotein models to emulate nature's energy conversion process using state-of-the-art equipment. The models have the potential to lead to efficient molecular-based solar-energy systems and possibly molecular-based computers that derive their energy from synthetic metalloproteins.
