SRP14 Antibody (PA5-27554) in WB

Western blot analysis of SRP14 in wild-type (WT) and SRP14 knockout (KO) 293T cell extracts (30 µg). Samples were incubated with SRP14 polyclonal antibody (Product # PA5-27554) using a dilution of 1:500 followed by HRP-conjugated anti-rabbit IgG. Separated by 15% SDS-PAGE.

Please note: We are reviewing Western blot images included in the antibody testing data in our catalog, including those provided by third parties. Unless expressly labeled or annotated as “raw-unedited”, Western blot images included in the antibody testing data in our catalog may have been edited, optimized or otherwise adjusted for presentation.

SRP14 Antibody — Figure 4. SRP mediated targeting to the ER ensures efficient spicing of XBP1u mRNA. ( A ) HEK 293 cells were transfected with shRNAs against luciferase (control), SRP14, or SRP54. 5 days after transfection, the cells were replated for transfection with XBP1u and treated with 10 mM DTT for the indicated time periods. The Trizol harvested cells were analyzed as in Figure 2D . A phos-tag gel was used for the Ire1alpha immunoblot. p-Ire1alpha and p-PERK indicate the phosphorylated forms of Ire1alpha and PERK, respectively. * denotes a background band. ( B ) HeLa cells were transfected with control siRNA or siRNA targeting the alpha subunit of the SRP receptor (SRalpha) and analyzed as described in Figure 2D . ( C ) HeLa cells were transfected with the indicated siRNA oligos and treated with 10 mM DTT for 2 hr after 96 hr post-transfection. Cells were harvested in SDS sample buffer and analyzed for IB with indicated antibodies. Upon DTT treatment, the ATF6alpha band disappears due to the cleavage of its N-terminal cytosolic domain. Our ATF6alpha antibodies were not suitable for detecting the cleaved N-terminal cytosolic domain (not shown). Note that depletion of Sec61alpha caused significant reduction of the transmembrane proteins PERK and ATF6alpha. DOI: http://dx.doi.org/ {KD}

Target Information

Signal-recognition-particle assembly has a crucial role in targeting secretory proteins to the rough endoplasmic reticulum membrane. SRP9 together with SRP14 and the Alu portion of the SRP RNA, constitutes the elongation arrest domain of SRP. The complex of SRP9 and SRP14 is required for SRP RNA binding.
