Descripción

General description

This product corresponds to ATCC Cat. No. HTB-96.

U2OS GFP-TUBA1B are osteosarcoma, epithelial cells, from a human caucasian female (aged 15 years), with a GFP-tagged modification.

K-α1 tubulin/ tubulin α 1b (TUBA1B) is a microtubule protein. It is a ~50 kDa protein in its poly glycosylated, post-translational form. TUBA1B is present in cells as one of the six different isotypes. This gene is located on human chromosome 12q13.12.

Application

This product is a human U2OS cell line in which the genomic TUBA1B gene has been endogenously tagged with a Green Fluorescent Protein (GFP) gene using CompoZr^® Zinc Finger Nuclease technology. Integration resulted in endogenous expression of the fusion protein in which GFP is attached to the N-terminus of tubulin. Fluorescence imaging shows that the tubulin can polymerize to form the characteristic pattern of microtubules. Addition of vincristine to this cell line shows the expected depolymerization of microtubules. This stable cell line was expanded from a single clone. The target′s gene regulation and corresponding protein function are preserved in contrast to cell lines with overexpression via an exogenous promoter.

Biochem/physiol Actions

K-α1 tubulin/ tubulin α 1b (TUBA1B) participates in several cellular activities like GTP binding, GTPase activity, maintaining cellular structure in the form of microtubules and microtubule-based intracellular movement. It plays a crucial role in polymerization and depolymerization during cell replication and division. TUBA1B is overexpressed in hepatocellular carcinoma (HCC) tumor tissues and proliferating HCC cells.

Tubulin α 1b (TUBA1B) plays an important role in dynamic process of polymerization and depolymerization during cell replication and division. Elevated expression of the gene has been observed in hepatocellular carcinoma (HCC) tumor tissues and proliferating HCC cells. This upregulated expression of the gene leads to poor prognosis and chemotherapy resistance in HCC.

Features and Benefits

GFP-tagged on chromosome 12q13.12

The U2OS cells are adherent, with a doubling time of approx. 29 hours.

Preparation Note
