Fibulin-3 Protein, Human (HEK293, His)

Customer Review

Based on 1 Customer Validation

Fibulin-3 protein can bind to the EGF receptor (EGFR), stimulate EGFR autophosphorylation and activate downstream signaling pathways. It may act as a negative regulator of chondrocyte differentiation, affecting cell adhesion and migration. Fibulin-3 Protein, Human (HEK293, His) is the recombinant human-derived Fibulin-3 protein, expressed by HEK293 , with N-His labeled tag.

Biological Activity

Description

Fibulin-3 protein can bind to the EGF receptor (EGFR), stimulate EGFR autophosphorylation and activate downstream signaling pathways. It may act as a negative regulator of chondrocyte differentiation, affecting cell adhesion and migration. Fibulin-3 Protein, Human (HEK293, His) is the recombinant human-derived Fibulin-3 protein, expressed by HEK293 , with N-His labeled tag.

Background

Fibulin-3 protein exhibits the ability to bind to the EGF receptor (EGFR), stimulating EGFR autophosphorylation and subsequent activation of downstream signaling pathways. It is thought to have implications in cell adhesion and migration, and may function as a negative regulator of chondrocyte differentiation. In the olfactory epithelium, Fibulin-3 protein potentially regulates glial cell migration and differentiation, as well as influences the capacity of glial cells to support neuronal neurite outgrowth. It interacts with ECM1 and TIMP3 proteins.
