APMAP interacts with LOXL1 and 3 and influences their expression level.
A) Protein expression of LOXL3 in eWAT of HFD-fed
ApmapE1-KO and WT mice; n = 3–4. B)
mRNA expression of Lox, Loxl1, and Loxl3 in eWAT; n ≥
4. C–E) Interaction of APMAP_E1 with LOXL1
(C), LOXL3 (D), and LOX
(E) in COS7 cells. Pulldown was performed with flag beads.
COS7 cells were transfected with Loxl1/-3-flag or Apmap-flag vectors and
His-Apmap or His-Lox vector. Empty pCMV 5.1 flag and His-LacZ
served as controls. One representative pulldown of n ≥
3 is shown. F) Scheme of APMAP full-length and truncated
protein variants. TM, transmembrane region. G, H) Flag beads
pulldown with LOXL1-flag (G) and LOXL3-flag
(H) and APMAP_E1 and truncated variants (E2, -3, -6) in
COS7 cells. *P ≤ 0.05,
**P ≤ 0.01 (Student’s
t test).
