The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 2 µg/ml.
Use a concentration of 20 µg/ml.
Use a concentration of 1 - 2 µg/ml. Detects a band of approximately 35 kDa.
FunctionIsoform Alpha is a retrovirus restriction factor, which mediates species-specific, early block to retrovirus infection. Targets retroviral capsid soon after entry into the cell, and prevents reverse transcription of the virus RNA genome. Isoform Alpha trimers may make multiple contacts with the hexameric lattice of CA proteins which constitute the surface of retrovirion core, and somehow inactivate the virus. Restricts efficiently infection by N-MLV, but not HIV-1. May have E3 ubiquitin-protein ligase activity.
PathwayProtein modification; protein ubiquitination.
Sequence similaritiesBelongs to the TRIM/RBCC family. Contains 1 B box-type zinc finger. Contains 1 B30.2/SPRY domain. Contains 1 RING-type zinc finger.
DomainThe RING-type zinc finger domain mediates binding to an E2 ubiquitin-conjugating enzyme.
Post-translational modificationsUbiquitinates itself in a RING finger- and UBE2D2-dependent manner (in vitro).
