Organism

Homo sapiens (Human)

Taxonomic identifier

9606 [NCBI]

Taxonomic lineage

Eukaryota › Metazoa › Chordata › Craniata › Vertebrata › Euteleostomi › Mammalia › Eutheria › Euarchontoglires › Primates › Haplorrhini › Catarrhini › Hominidae › Homo

Protein attributes

Sequence length	924 AA.
Sequence status	Complete.
Protein existence	Evidence at transcript level

General annotation (Comments)

Function	Plays a role in autophagy By similarity.
Subcellular location	Cytoplasmic vesicle › autophagosome membrane; Multi-pass membrane protein By similarity.
Tissue specificity	Highly expressed in placenta (trophoblast cells) and pituitary gland. Not expressed in vascular endothelial. Ref.1
Induction	By hypoxia, leading to inhibit NOS3 expression. Ref.6
Miscellaneous	ATG9B gene is located on the opposite DNA strand of the NOS3 gene at chromosome 7q36. The genes are oriented in a tail-to-tail configuration and the mRNAs encoding ATG9B and NOS3 are complementary for 662 nucleotides. ATG9B transcription may a role in NOS3 transcription regulation.
Sequence similarities	Belongs to the ATG9 family.
Sequence caution	The sequence AAQ86941.1 differs from that shown. Reason: Erroneous initiation. The sequence AC010973 differs from that shown. Reason: Frameshift at position 766.
