Recombinant Human VAV1, GST-tagged

• Cat.No.: VAV1-163H
• Product Overview: Recombinant human VAV1 (73-end) was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag.

Specification

• Species: Human
• Source: Sf9 Cells
• Tag: GST
• Protein Length: 73-end a.a.
• Description: VAV1 is a member of the VAV gene family which are guanine nucleotide exchange factors (GEFs) for Rho family GTPases. VAV1 activates pathways leading to actin cytoskeletal rearrangements and transcriptional alterations. VAV1 is important in hematopoiesis, playing a role in T-cell and B-cell development and activation. VAV1 has been identified as the specific binding partner of Nef proteins from HIV-1. Co-expression and binding of Nef with VAV1 initiates profound morphological changes, cytoskeletal rearrangements and the JNK/SAPK signaling cascade, leading to increased levels of viral transcription and replication.VAV1 proto-oncogene participates in the signaling processes that mediate the antigen-induced activation of B lymphocytes.
• Form: Recombinant protein stored in 50mM Tris-HCl, pH 7.5, 50mM NaCl, 10mM glutathione, 0.1mM EDTA, 0.25mM DTT, 0.1mM PMSF, 25% glycerol.
