| FUNCTION: Receptor tyrosine kinase which binds promiscuously membrane-bound ephrin family ligands residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. The signaling pathway downstream of the receptor is referred to as forward signaling while the signaling pathway downstream of the ephrin ligand is referred to as reverse signaling. Highly promiscuous for ephrin-A ligands it binds preferentially EFNA5. Upon activation by EFNA5 regulates cell-cell adhesion, cytoskeletal organization and cell migration. Plays a role in cardiac cells migration and differentiation and regulates the formation of the atrioventricular canal and septum during development probably through activation by EFNA1. Involved in the retinotectal mapping of neurons. May also control the segregation but not the guidance of motor and sensory axons during neuromuscular circuit development. {ECO:0000269|PubMed:11870224}. | FUNCTION: 3'-to-5'exoribonuclease that preferentially degrades DNA and RNA oligonucleotides composed of only two nucleotides (PubMed:31588022, PubMed:30926754, PubMed:32365187, PubMed:23741365). Binds and degrades longer oligonucleotides with a lower affinity (PubMed:31588022, PubMed:30926754, PubMed:32365187). Plays dual roles in mitochondria, scavenging nanoRNAs (small RNA oligonucleotides of <5 nucleotides) that are produced by the degradosome and clearing short RNAs that are generated by RNA processing (PubMed:31588022, PubMed:30926754, PubMed:32365187). Essential for correct initiation of mitochondrial transcription, degrading mitochondrial RNA dinucleotides to prevent RNA-primed transcription at non-canonical sites in the mitochondrial genome (PubMed:31588022). Essential for embryonic development (By similarity). {ECO:0000250|UniProtKB:Q9D8S4, ECO:0000269|PubMed:23741365, ECO:0000269|PubMed:30926754, ECO:0000269|PubMed:31588022, ECO:0000269|PubMed:32365187}.; FUNCTION: [Isoform 3]: 3'-to-5'exoribonuclease that preferentially degrades DNA and RNA oligonucleotides composed of only two nucleotides. {ECO:0000269|PubMed:10851236, ECO:0000269|PubMed:16682444}. |
| Retention analysis result of each fusion partner protein across 39 protein features of UniProt such as six molecule processing features, 13 region features, four site features, six amino acid modification features, two natural variation features, five experimental info features, and 3 secondary structure features. Here, because of limited space for viewing, we only show the protein feature retention information belong to the 13 regional features. All retention annotation result can be downloaded at * Minus value of BPloci means that the break pointn is located before the CDS. |
