Human Gene ABCF1 (uc011gtb.2) Description and Page Index
  Description: Homo sapiens ATP-binding cassette, sub-family F (GCN20), member 1 (ABCF1), transcript variant 1, mRNA.
RefSeq Summary (NM_001025091): The protein encoded by this gene is a member of the superfamily of ATP-binding cassette (ABC) transporters. ABC proteins transport various molecules across extra- and intra-cellular membranes. ABC genes are divided into seven distinct subfamilies (ABC1, MDR/TAP, MRP, ALD, OABP, GCN20, White). This protein is a member of the GCN20 subfamily. Unlike other members of the superfamily, this protein lacks the transmembrane domains which are characteristic of most ABC transporters. This protein may be regulated by tumor necrosis factor-alpha and play a role in enhancement of protein synthesis and the inflammation process. [provided by RefSeq, Jul 2008].

-  Comments and Description Text from UniProtKB
DESCRIPTION: RecName: Full=ATP-binding cassette sub-family F member 1; AltName: Full=ATP-binding cassette 50; AltName: Full=TNF-alpha-stimulated ABC protein;
FUNCTION: Isoform 2 is required for efficient Cap- and IRES- mediated mRNA translation initiation. Isoform 2 is not involved in the ribosome biogenesis.
SUBUNIT: Isoform 2 interacts (via N-terminus) with EIF2S1; the interaction is independent of its phosphorylated status. Isoform 2 associates (via both ABC transporter domains) with the ribosomes.
SUBCELLULAR LOCATION: Isoform 2: Cytoplasm. Nucleus, nucleoplasm. Nucleus envelope.
INDUCTION: By TNF in cultured synoviocytes.
PTM: Isoform 2 is phosphorylated at phosphoserine and phosphothreonine. Isoform 2 phosphorylation on Ser-109 and Ser-140 by CK2; inhibits association of EIF2 with ribosomes.
SIMILARITY: Belongs to the ABC transporter superfamily. ABCF family. EF3 subfamily.
SIMILARITY: Contains 2 ABC transporter domains.

    We identified and then confirmed through replication two new genetic loci for SLE: a promoter-region allele associated with reduced expression of BLK and increased expression of C8orf13 and variants in the ITGAM-ITGAX region.

ModBase Predicted Comparative 3D Structure on Q8NE71
The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
