The granin family is a driving force in LDCV biogenesis, but the machinery for granin sorting to this biogenesis pathway is largely unknown. The mu mutant mouse, which carries a spontaneous null mutation on the Muted gene (also known as Bloc1s5), which encodes a subunit of the biogenesis of lysosome-related organelles complex-1 (BLOC-1), is a mouse model of Hermansky\u2013Pudlak syndrome. Here, we found that LDCVs were enlarged in mu adrenal chromaffin cells. Chromogranin A (CgA, also known as CHGA) was increased in mu adrenals and muted-knockdown cells. The increased CgA in mu mice was likely due a failure to export this molecule out of immature LDCVs, which impairs LDCV maturation and docking. In mu chromaffin cells, the size of readily releasable pool and the vesicle release frequency were reduced. Our studies suggest that the muted protein is involved in the selective export of CgA during the biogenesis of LDCVs.<\/jats:p>","DOI":"10.1242\/jcs.161414","type":"journal-article","created":{"date-parts":[[2015,2,12]],"date-time":"2015-02-12T00:00:03Z","timestamp":1423699203000},"page":"1365-1374","source":"Crossref","is-referenced-by-count":17,"title":["Impaired maturation of large dense-core vesicles in muted-deficient adrenal chromaffin cells"],"prefix":"10.1242","volume":"128","author":[{"given":"Zhenhua","family":"Hao","sequence":"first","affiliation":[{"name":"State Key Laboratory of Molecular Developmental Biology, Institute of Genetics & Developmental Biology, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"University of Chinese Academy of Sciences, Beijing 100039, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisi","family":"Wei","sequence":"additional","affiliation":[{"name":"Institute of Molecular Medicine and State Key Laboratory of Biomembrane Engineering, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yaqin","family":"Feng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Molecular Developmental Biology, Institute of Genetics & Developmental Biology, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"Department of Histology and Embryology, Shanxi Medical University, Taiyuan 030001, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaowei","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Molecular Medicine and State Key Laboratory of Biomembrane Engineering, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wen","family":"Du","sequence":"additional","affiliation":[{"name":"Institute of Biophysics, Chinese Academy of Sciences, Beijing 100101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Ma","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Molecular Developmental Biology, Institute of Genetics & Developmental Biology, Chinese Academy of Sciences, Beijing 100101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhuan","family":"Zhou","sequence":"additional","affiliation":[{"name":"Institute of Molecular Medicine and State Key Laboratory of Biomembrane Engineering, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liangyi","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Molecular Medicine and State Key Laboratory of Biomembrane Engineering, Peking University, Beijing 100871, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Li","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Molecular Developmental Biology, Institute of Genetics & Developmental Biology, Chinese Academy of Sciences, Beijing 100101, China"},{"name":"Center of Alzheimer's Disease, Beijing Institute for Brain Disorders, Beijing 100053, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"237","reference":[{"key":"2021111216231982200_b1","doi-asserted-by":"publisher","first-page":"4563","DOI":"10.1091\/mbc.E09-04-0272","article-title":"HOPS interacts with Apl5 at the vacuole membrane and is required for consumption of AP-3 transport vesicles.","volume":"20","author":"Angers","year":"2009","journal-title":"Mol.
