General description

The Arabidopsis thaliana Rab GTPase (RabA4b) is a Rab GTPase, that is expressed in various plant organs. In A. thaliana, RabA4b is ubiquitously expressed, mainly located at an inverted cone-shaped area in the apical region in the root hairs. The Arabidopsis genome contains a total of 93 small GTPase genes, including 57 members of the Rab family. Arabidopsis thaliana Rab GTPase RabA4b (AtRabA4b, AtGB3, AtRab11G) is highly similar to AtRab11.


Anti-AtRabA4bspecifically recognizes recombinant AtRabA4b fusion protein.


synthetic peptide corresponding to amino acids 201-219 located near the C-terminus of Arabidopsis thaliana AtRabA4b fusion protein.


Anti-AtRabA4 antibody produced in rabbit may be used in immunoblotting.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, and 15 mM sodium azide.

Storage and Stability

For continuous use, store at 2-8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

Biochem/physiol Actions

The Arabidopsis thaliana Rab GTPase (RabA4b) can control membrane trafficking steps involved in the polarized deposition of cell wall components in tip-growing root hair cells. AtRabA4b can label the trans-Golgi network compartment displaying a developmentally regulated polar distribution in growing root hair cells of A. thaliana.
