General annotation (Comments)

Function	Involved in late endocytic transport. Contributes to the maturation of phagosomes (acidification). Ref.8 Ref.10
Subunit structure	Interacts with RILP. Ref.8 Ref.11
Subcellular location	Late endosome. Lysosome. Cytoplasmic vesicle › phagosome. Melanosome. Note: Identified by mass spectrometry in melanosome fractions from stage I to stage IV. Ref.10 Ref.9 Ref.13
Tissue specificity	Widely expressed; high expression found in skeletal muscle. Ref.17
Involvement in disease	Defects in RAB7A are the cause of Charcot-Marie-Tooth disease type 2B (CMT2B) [MIM:600882]; also known as hereditary motor and sensory neuropathy II (HMSN2). CMT2B is a form of Charcot-Marie-Tooth disease, the most common inherited disorder of the peripheral nervous system. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathy or CMT1, and primary peripheral axonal neuropathy or CMT2. Neuropathies of the CMT2 group are characterized by signs of axonal regeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. CMT2B is clinically characterized by marked distal muscle weakness and a high frequency of foot ulcers, infections and amputations of the toes. CMT2B inheritance is autosomal dominant. Ref.17 Ref.18 Ref.19
Sequence similarities	Belongs to the small GTPase superfamily. Rab family.
Sequence caution	The sequence BAA91390.1 differs from that shown. Reason: Erroneous translation. Wrong choice of frame. The sequence BAF83410.1 differs from that shown. Reason: Erroneous translation. Wrong choice of frame. The sequence EAW79303.1 differs from that shown. Reason: Erroneous gene model prediction.
