MyBioSource.com's KALRN Antibody is a Rabbit Polyclonal antibody. This antibody has been shown to work in applications such as: ELISA, Immunocytochemistry, Immunofluorescence, Immunohistochemistry, and Western Blot. The KALRN Antibody was generated using KALRN as the antigen and it reacts with Human, Mouse, and Rat.
Description
Function: Promotes the exchange of GDP by GTP. Activates specific Rho GTPase family members, thereby inducing various signaling mechanisms that regulate neuronal shape, growth, and plasticity, through their effects on the actin cytoskeleton. Induces lamellipodia independent of its GEF activity.
Subunit Structure: Interacts with the C-terminal of peptidylglycine alpha-amidating monooxygenase (PAM) and with the huntingtin-associated protein 1 (HAP1) (By similarity). Interacts with FASLG.
Post-translational Modifications: Autophosphorylated.
Similarity: The two GEF domains catalyze nucleotide exchange for RAC1 and RhoA which are bound by DH1 and DH2 respectively. The two GEF domains appear to play differing roles in neuronal development and axonal outgrowth. SH3 1 binds to the first GEF domain inhibiting GEF activity only when in the presence of a PXXP peptide, suggesting that the SH3 domain/peptide interaction mediates binding to GEF1. CRK1 SH3 domain binds to and inhibits GEF1 activity (By similarity). Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family
