3.A.1.209.3
Haf-4/Haf-9 heterodimeric half transporter of 787 aas and 815 aas, respectively.  Probably tranports antigenic peptides. Both proteins localize to the membrane of nonacidic, lysosome-associated, membrane protein homologue (LMP-1)-positive intestinal granules from larval to adult stages. Mutants of haf-4 and haf-9 exhibited granular defects in late larval and young adult intestinal cells, associated with decreased brood size, prolonged defecation cycle, and slow growth (Kawai et al. 2009). Thus they may mediate intestinal granular formation. HAF-4-HAF-9 heterodimer formation is required for their stabilization (Tanji et al. 2013). The HAF-4- and HAF-9-localizing organelles are distinct intestinal organelles associated with the endocytic pathway (Tanji et al. 2016; Tanji et al. 2017).
