Description
OverviewRecognizes the ~22 kDa RhoA protein, expressed as a GST fusion protein (total ~49 kDa) and phosphorylated in vitro by PKA.
Catalogue NumberPS1089
Brand Family Calbiochem®
Application Data
Detection of human RhoA, phosphorylated at Ser188, by immunoblotting. Samples: RhoA GST fusion protein left unphosphorylated (lanes 1,3) or phosphorylated in vitro by PKA (lanes 2,4,5,6). Primary antibodies: Anti-RhoA (detecting total Rho; lanes 1,2) and PhosphoDetect™ Anti-RhoA (pSer188) (Cat. No. PS1089) (1:1000) preincubated without blocking peptide (lanes 3,4), preincubated with phosphoRhoA (pSer188) blocking peptide (lane 5), and preincubated with nonspecific phosphoserine containing blocking peptide (lane 6). Detection: chemiluminescence.

Applications
Key Applications Enzyme-Linked Immunosorbent Assay
Immunoblotting (Western Blotting)
Application NotesImmunoblotting (1:1000)
ELISA (1:2000)
Application CommentsDoes not recognize unphosphorylated RhoA. The immunogen sequence is conserved in rat and mouse RhoA, but cross-reactivity has not been tested. The immunogen sequence is not found in the RhoB and RhoC sequences. For immunoblotting, the membrane was incubated with antibody diluted in PBS/5% nonfat milk/0.04% Tween® 20 detergent for 1 h at room temperature. Antibody should be titrated for optimal results in individual systems.

DescriptionImmunoaffinity purified rabbit polyclonal antibody. Recognizes the ~22 kDa RhoA protein when expressed as a GST fusion protein (total ~49 kDa) and phosphorylated in vitro by PKA.
BackgroundRho (A, B, and C) proteins are members of the Ras superfamily of GTPases. They regulate a variety of cellular functions, including cell cycle progression, cytoskeletal rearrangement, and gene expression. Rho cycles between the active GTP-bound form and the inactive GDP-bound form. Conversion from the inactive to the active form and vice versa is controlled by guanine nucleotide exchange factors (GEFs) and GTPase-activating proteins (GAPs). The three Rho proteins are highly homologous and contain the consensus sequences necessary for GDP/GTP binding and GTPase activity. RhoA is phosphorylated at Ser188 in vitro by PKA and PKG. This phosphorylation enhances RhoGDI binding and inhibits RhoA-mediated stress fiber formation, indicating that Ser188 is an important site for negative regulation of RhoA activity.
