Human Gene TWF1 (ENST00000395510.7) from GENCODE V44
Description: Homo sapiens twinfilin actin binding protein 1 (TWF1), transcript variant 2, mRNA. (from RefSeq NM_002822) RefSeq Summary (NM_002822): This gene encodes twinfilin, an actin monomer-binding protein conserved from yeast to mammals. Studies of the mouse counterpart suggest that this protein may be an actin monomer-binding protein, and its localization to cortical G-actin-rich structures may be regulated by the small GTPase RAC1.

Gencode Transcript: ENST00000395510.7 Gencode Gene: ENSG00000151239.14 Transcript (Including UTRs) Position: hg38 chr12:43,793,723-43,806,317 Size: 12,595 Total Exon Count: 9 Strand: - Coding Region Position: hg38 chr12:43,795,585-43,806,245 Size: 10,661 Coding Exon Count: 9
ID:TWF1_HUMAN DESCRIPTION: RecName: Full=Twinfilin-1; AltName: Full=Protein A6; AltName: Full=Protein tyrosine kinase 9; FUNCTION: Actin-binding protein involved in motile and morphological processes. Inhibits actin polymerization, likely by sequestering G-actin. By capping the barbed ends of filaments, it also regulates motility. Seems to play an important role in clathrin-mediated endocytosis and distribution of endocytic organelles (By similarity). SUBUNIT: Interacts with G-actin; ADP-actin form and capping protein (CP). May also be able to interact with TWF2 and phosphoinositides, PI(4,5)P2. When bound to PI(4,5)P2, it is down- regulated (By similarity). SUBCELLULAR LOCATION: Cytoplasm. Cytoplasm, cytoskeleton (By similarity). Note=Diffuse cytoplasmic localization with perinuclear and G-actin-rich cortical actin structures sublocalization. Also found at membrane ruffles and cell-cell contacts (By similarity). TISSUE SPECIFICITY: Expressed at high levels in the colon, testis, ovary, prostate and lung. Expressed at lower levels in the brain, bladder and heart. Not detected in liver. PTM: Phosphorylated on serine and threonine residues. SIMILARITY: Belongs to the actin-binding proteins ADF family. Twinfilin subfamily. SIMILARITY: Contains 2 ADF-H domains. CAUTION: Was originally (PubMed:7507208) thought to have protein tyrosine kinase activity. SEQUENCE CAUTION: Sequence=AAH43148.2; Type=Erroneous initiation; Sequence=AAH68548.1; Type=Erroneous initiation; Sequence=BAD92539.1; Type=Erroneous initiation; WEB RESOURCE: Name=Protein Spotlight; Note=Molecular embrace - Issue 73 of August 2006; URL="http://web.expasy.org/spotlight/back_issues/sptlt073.shtml";
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

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.
