Functions of the retinoblastoma protein

BioEssays, 1999
The retinoblastoma protein (pRB) can both positively and negatively regulate transcription. The former correlates with its ability to promote differentiation and the latter with its ability to regulate entry into S-phase. pRB negatively regulates transcription by forming complexes with members of the E2F transcription factor family.

Protein Ubiquitylation and Synaptic Function

Annals of the New York Academy of Sciences, 2003
Abstract: Conjugation of ubiquitin to proteins is a well‐established signal to regulate an ever expanding range of cellular processes. Here, we discuss recent findings that deeply link ubiquitin signaling to synaptic activity.

Protein-Functionalized Polymer Brushes

Biomacromolecules, 2005
A new strategy for the preparation of protein-functionalized polymer brushes is reported, which is based on a combination of surface-initiated atom transfer radical polymerization (ATRP), p-nitrophenyl chloroformate activation of the surface hydroxyl groups, and subsequent O(6)-benzylguanine (BG) functionalization.

Prediction of Protein Functions

2011
The recent explosion in the number and diversity of novel proteins identified by the large-scale "omics" technologies poses new and important questions to the blossoming field of systems biology--what are all these proteins, how did they come about, and most importantly, what do they do? From a comparatively small number of protein structural domains a

Proteins: Dynamics and Function

1988
The focus in my paper changes from the genes to gene products, which are proteins. I will describe some of the results of theoretical methods that are used to understand the functioning of these gene products. Since there is no plan for a “human protein consortium,” I will restrict myself to describing what has been going on in this area.

Protein Function

2021
This chapter evaluates the wide variety of ways that proteins support the structures and life processes of viruses, cells, and organisms. It begins by looking at structural proteins, enzymes and enzyme kinetics, and antibodies. The chapter then considers transmembrane transport proteins—including channels, gates, and pumps—and receptors, all embedded ...

Functional Mapping of Surfactant Protein A

Fetal and Pediatric Pathology, 2001
Surfactant protein A (SP-A) is a highly ordered, oligomeric glycoprotein that is secreted into the airspaces of the lung by alveolar type II cells and Clara cells of the pulmonary epithelium. Although research has shown that SP-A is both a calcium-dependent phospholipid-binding protein that affects surfactant structure and function and a lectin that ...

Protein Function

1997
Abstract The companion to this book, Protein Structure: A Practical Approach, gives methods of determining the structure of a newly discovered protein, but that is only part of the story. Protein Function: A Practical Approach completes the picture by providing the techniques for elucidating the functional properties of proteins, which ...
