Hydrolyzes UDP-glucose to glucose 1-phosphate and UMP and ADP-ribose to ribose 5-phosphate and AMP. The physiological substrate is probably UDP-glucose. Poor activity on other substrates such as ADP-glucose, CDP-glucose, GDP-glucose and GDP-mannose.
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).

We have performed an exhaustive unbiased yeast two-hybrid analysis to identify interaction partners of two human Raf kinase isoforms, A-Raf and C-Raf, using their N-terminal regulatory domain as "bait." A total of 20 different human proteins were found to interact with Raf isoforms. Several of these interactions were novel and an extensive bioinformatics evaluation was performed for each. The novel putative interactions include a signalosome component, TOPK/PBK kinase, and two new putative protein phosphatases. The cysteine-rich zinc-binding domain (CRD) of Raf was found to interact with all 20 proteins and to achieve isoform-specific interactions. Since similar putative CRDs are present in a variety of protein serine-threonine kinases, the data suggest that the CRD may function as a major protein-protein interaction domain of these kinases. We propose possible functional consequences of these novel Raf interactions.
Enzyme which catalyzes hydrolysis reaction, i.e. the addition of the hydrogen and hydroxyl ions of water to a molecule with its consequent splitting into two or more simpler molecules.
A reference proteome is a set of protein sequences derived from a complete proteome which constitutes a defined standard for a particular user community. Reference proteomes are manually defined according to a number of criteria. They cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical and biotechnological research. Reference proteomes have been selected to provide broad coverage of the tree of life, and constitute a representative cross-section of the taxonomic diversity to be found within UniProtKB.
