General annotation (Comments)

Function	Component of the ESCRT-I complex, a regulator of vesicular trafficking process. Required for the sorting of endocytic ubiquitinated cargos into multivesicular bodies. May be involved in cell growth and differentiation. Ref.6
Subunit structure	Component of the ESCRT-I complex (endosomal sorting complex required for transport I) which consists of TSG101, VPS28, a VPS37 protein (VPS37A to -D) and a FAM125/MVB12 protein (FAM125A or -B) in a 1:1:1:1 stoechiometry. Interacts with TSG101, VPS28 and HGS. Ref.5 Ref.6 Ref.7
Subcellular location	Late endosome membrane; Peripheral membrane protein. Nucleus Ref.1 Ref.6.
Tissue specificity	Widely expressed, but more abundant in liver. Strongly decreased or undetected in hepatomas. Ref.1
Sequence similarities	Belongs to the VPS37 family. Contains 1 VPS37 C-terminal domain.
Sequence caution	The sequence AAH22363.1 differs from that shown. Reason: Erroneous initiation.
