HER3 Protein, Human (sf9, His-GST)

HER3, a pivotal tyrosine-protein kinase, acts as a crucial cell receptor for neuregulins. Neuregulin-1 (NRG1) activation boosts tyrosine phosphorylation and interaction with p85 subunit of phosphatidylinositol 3-kinase. CSPG5 may also activate HER3. Its involvement in myeloid cell differentiation underscores HER3's vital role in essential cellular processes for normal development and function. HER3 Protein, Human (sf9, His-GST) is the recombinant human-derived HER3 protein, expressed by Sf9 insect cells , with N-His, N-GST labeled tag. The total length of HER3 Protein, Human (sf9, His-GST) is 336 a.a., with molecular weight of ~65 kDa.

HER3, a tyrosine-protein kinase, serves as a critical cell surface receptor for neuregulins. Activated by neuregulin-1 (NRG1), ligand binding enhances phosphorylation on tyrosine residues and facilitates its interaction with the p85 subunit of phosphatidylinositol 3-kinase. Additionally, there is evidence suggesting activation by CSPG5. HER3 is intricately involved in the regulation of myeloid cell differentiation, highlighting its pivotal role in cellular processes crucial for normal development and function.
