Protein attributes
| Sequence length | 723 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | E3 ubiquitin-protein ligase that mediates monoubiquitination of TSG101 at multiple sites, leading to inactivate the ability of TSG101 to sort endocytic (EGF receptors) and exocytic (HIV-1 viral proteins) cargos. Ref.5 |
| Pathway | |
| Subunit structure | Interacts with TSG101. Ref.6 |
| Subcellular location | Cytoplasm. Note: Displays a punctuate distribution and localizes to a submembranal ring. Ref.5 |
| Tissue specificity | Highly expressed in adult spinal cord motoneurons as well as in fetal spinal cord and muscle tissue. Ref.11 |
| Domain | The coiled coil domains interact with the SB domain of TSG101. Ref.5 The PTAP motifs mediate the binding to UEV domains. Ref.5 |
| Involvement in disease | Charcot-Marie-Tooth disease 2P (CMT2P) [MIM:614436]: An axonal form of Charcot-Marie-Tooth disease, a disorder of the peripheral nervous system, characterized by progressive weakness and atrophy, initially of the peroneal muscles and later of the distal muscles of the arms. Charcot-Marie-Tooth disease is classified in two main groups on the basis of electrophysiologic properties and histopathology: primary peripheral demyelinating neuropathies (designated CMT1 when they are dominantly inherited) and primary peripheral axonal neuropathies (CMT2). Neuropathies of the CMT2 group are characterized by signs of axonal degeneration in the absence of obvious myelin alterations, normal or slightly reduced nerve conduction velocities, and progressive distal muscle weakness and atrophy. Nerve conduction velocities are normal or slightly reduced. |
| Sequence similarities | Contains 6 LRR (leucine-rich) repeats. Contains 1 RING-type zinc finger. Contains 1 SAM (sterile alpha motif) domain. |
Ontologies
Alternative products
| This entry describes 3 isoforms produced by alternative splicing. [Align] [Select] | ||||||
| Isoform 1 (identifier: Q6UWE0-1) This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry. | ||||||
| Isoform 2 (identifier: Q6UWE0-2) The sequence of this isoform differs from the canonical sequence as follows: 474-500: Missing. | ||||||
| Isoform 3 (identifier: Q6UWE0-3) The sequence of this isoform differs from the canonical sequence as follows: 1-420: Missing. | ||||||
| Note: No experimental confirmation available. |
