WebNov 26, 2024 · Therefore Rab14-MARylation determines the sequential binding of this GTPase to RUFY and FIP1c, thus controlling endosome progression ( i. e ., transferrin receptors recycling) through the Rab4-, Rab14- and Rab11-specific vesicles. This identifies a Rab14-specific compartment of the recycling pathway and a crucial enzymatic reaction … WebRab11-FIP1C, as a probe to identify a key motif in the Env cy-toplasmic tail that is essential for Env incorporation into par-ticles. We show that this motif governs the cell-type–specific incorporation of Env into particles and the appearance of Env at the particle budding site. Our results provide key insights

WebFIP1C was redistributed out of the endosomal recycling complex to the plasma membrane by wild type Env protein but not by CT-truncated Env. Rab14 was required for HIV-1 Env … WebJun 5, 2024 · To determine whether FIP1C is required for Env incorporation and HIV-1 replication in physiologically relevant cells, CRISPR/Cas9 technology was used to knock out the expression of this protein in several human T-cell lines – Jurkat E6.1, SupT1 and H9 – and in primary human CD4+ T cells. FIP1C knock-out caused modest reductions in Env ...
WebJun 1, 2006 · Rab11-FIP1C/RCP is 98% homologous to RCP (AF368294).

WebFIP1C mutants incapable of binding Rab14 failed to rescue Env incorporation. Expression of FIP1C and Rab14 led to an enhancement of Env incorporation, indicating that these trafficking factors are normally limiting for CT-dependent Env incorporation onto particles. These findings support a model for HIV-1 Env incorporation in which specific ...
