Additional Information

Additional information (application):

This antibody is also recognizing RPT2b protein.

Recommended western blot conditions: SDS-PAGE, transfer to nitrocellulose, blocking 10% non-fat milk. Diluent for both primary and secondary antibodies PBS containing 0.2% Tween 20 and 1% BSA.

For an image of western blot detection, refer to: Smalle et al. (2002).

Background

Background:

RPT2a (Regulatory particle triple-A ATPase subunit 2a) is the 26S proteasome subunit. It is required for root meristem maintenance, and regulates gametogenesis. RPT2a is also shown to regulate gene silencing via DNA methylation.

Alternative names: 26S proteasome regulatory subunit 4 homolog A Alternative name(s): 26S proteasome AAA-ATPase subunit, RPT2a 26S proteasome subunit 4 homolog A, Protein HALTED ROOT, 26S proteasome regulatory subunit 4 homolog A.
