Application

EC Number Application Comment Organism
2.4.1.212 medicine HAS1 variant Vc is transforming in vitro and tumorigenic in vivo when introduced as a single oncogene to untransformed cells. In co-transfected cells, full length HAS1 and HAS1 variants interact with themselves and with each other to form heteromeric multiprotein assemblies Homo sapiens

Expression

EC Number Organism Comment Expression
2.4.1.212 Homo sapiens comparison of full-length HAS1 isoform and its splice variants Va, Vb, and Vc. When co-expressed, the properties of HAS1 variants are dominant over those of full length HAS1. Full length HAS1 appears to be diffusely expressed in the cell, but HAS1 variants are concentrated in the cytoplasm and/or Golgi apparatus. HAS1 variants synthesize detectable de novo hyaluronan intracellularly. Each of the HAS1 variants is able to relocalize full length HAS1 protein from diffuse cytoskeleton-anchored locations to deeper cytoplasmic spaces. The HAS1-variants-mediated relocalization occurs through strong molecular interactions, which also serve to protect full length HAS1 from its otherwise high turnover kinetics additional information
