Sepharose 97-104 nerve growth factor Rattus norvegicus 50-69 7681142-5 1993 SNT was phosphorylated in vitro on serine, threonine, and tyrosine in p13suc1-agarose precipitates from NGF-treated PC12 cells, indicating that this protein may be a substrate of kinase activities associated with p13suc1-p34cdc2/cdk2 complexes. Sepharose 78-85 nerve growth factor Rattus norvegicus 104-107
