CC   -!- FUNCTION: Guanine nucleotide exchange factor (GEF) for RAB35 that acts
CC       as a regulator of T-cell receptor (TCR) internalization in TH2 cells.
CC       Acts by promoting the exchange of GDP to GTP, converting inactive GDP-
CC       bound RAB35 into its active GTP-bound form. Plays a role in clathrin-
CC       mediated endocytosis. Controls cytokine production in TH2 lymphocytes
CC       by controlling the rate of TCR internalization and routing to
CC       endosomes: acts by mediating clathrin-mediated endocytosis of TCR via
CC       its interaction with the adapter protein complex 2 (AP-2) and GEF
CC       activity. Dysregulation leads to impaired TCR down-modulation and
CC       recycling, affecting cytokine production in TH2 cells.
CC       {ECO:0000269|PubMed:26774822}.
CC   -!- SUBUNIT: Interacts with RAB35 (PubMed:26774822). Interacts with
CC       clathrin heavy chain/CLTC (By similarity). Interacts with components of
CC       the adapter protein complex 2 (AP-2) AP2A2 and AP2B1 (By similarity).
CC       Interacts with CD3E (PubMed:26774822). {ECO:0000250|UniProtKB:Q6P3S1,
CC       ECO:0000269|PubMed:26774822}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytosol
CC       {ECO:0000250|UniProtKB:Q6P3S1}. Cytoplasmic vesicle, clathrin-coated
CC       vesicle {ECO:0000250|UniProtKB:Q6P3S1}.

CC       {ECO:0000269|PubMed:26774822}.
CC   -!- DOMAIN: The clathrin box motif mediates interaction with clathrin.
CC       {ECO:0000269|PubMed:26774822}.
CC   -!- PTM: Phosphorylated on serine and/or threonine, possibly regulating the
CC       guanine nucleotide exchange factor (GEF) activity.
CC       {ECO:0000250|UniProtKB:Q6P3S1}.
CC   -!- DISRUPTION PHENOTYPE: Mice are developmentally normal and fertile but
CC       accumulate more splenic and lymph node CD4(+) and CD8(+)
CC       effector/memory T-cells with age. TH2 cells display increased TCR-
CC       mediated responses, due to delayed surface TCR down-modulation and
CC       recycling, and increased production of cytokines. Mice have increased
CC       antigen-induced allergic responses. {ECO:0000269|PubMed:26774822}.
