Fig. 3 Cloning and Characterization of Slc37a2, the Gene Underlying the blb Phenotype

(A) Schematic of the slc37a2 locus. Sequences of the NY007/t³⁰³⁰¹ allele (C/T mutation) and NA150/t³⁰⁹¹³ allele (T/A mutation).

(B) Dorsal view of a 4 dpf Slc37a2 knockout generated with CRISPR-Cas9 as shown in (A). Scale bar, 30 μm.

(C) Dorsal view of a representative immunostaining of a 4 dpf embryo where microglia are in green Tg(mpeg:GFP-caax) and Slc37a2 in red. Scale bar, 30 μm.

(D) Magnification of (C). Scale bar, 15 μm. The yellow arrow points to a phagosome positive for Slc37a2.

(E) Western blot analysis of Slc37a2 (55 kDa) and Tubulin (48 kDa) in wild-type, blb^NY007, and blb^NI150.

(F) Immunostainings of Slc37a2 (cyan) and Lamp1 (red) in RAW264.7. Scale bar, 5 μm.

(G and H) Mass-spectrometry data showing normalized intensities of glucose 6-phosphate (G) not significant, and D-gluconate-6-phosphate (H) significant, p value < 0.0001, in blbNY007 and wild-type.
