Fig. 8

Sec13^sq198 mutant protein is a C-terminal truncated Sec13 which is unable to interact with Sec31a. (A) Alignment of the C-terminal sequences of Sec13 and Sec13^sq198. Sec13^sq198 mutant protein lacks the C-terminus of Sec13 starting from D²³⁶ (blue arrow) and contains 34 new amino acids after Q²³⁵ (blue arrow). (B) Co-immunoprecipitation (Co-IP) analysis. HEK-293T cells were transfected with HA-SEC13 or HA-SEC13^sq198 plasmids. An anti-HA antibody was used to immunoprecipitate (IP) the tagged proteins. The input (1st and 2nd panels) and the IP products (3rd and 4th panels) were blotted using an anti-SEC31A antibody (2nd and 4th panels) and an anti-Sec13 mosue serum (1st and 3rd panels). (C-E) In human Hela cells, Myc-SEC13 (C) or zebrafish Myc-Sec13 (D) co-localizes with endogenous SEC31a whilst SEC13^sq198 is evenly distributed in the cytoplasm (E). (C1,D1,E1) Immunofluorescence staining of endogenous SEC31a (red). (C3,D3,E3) Immunostaining of Myc-tagged hSEC13 (C3) or zSec13 (D3) or hSEC13^sq198 (E3) (green). (C2,D2,E2) Superimposed.
