Gene RIF (14)

26362536 HIV-1 Gag interacts with PFFIA1 as demonstrated by proximity dependent biotinylation proteomics
25492966 results suggested that PPFIA1 functioned with PP2A to promote the dephosphorylation of Kif7, triggering Kif7 localization to the tips of primary cilia and promoting Gli transcriptional activity.
24982445 Liprin-alpha1, ERC1a and LL5 also define new highly polarized and dynamic cytoplasmic structures uniquely localized near the protruding cell edge
23453270 PPFIA1 was frequently co-amplified with the Cyclin D1 gene in oral carcinomas and could present a biomarker as well as a novel target for specific gene therapy.
22295056 PPFIA1 as a potential functional candidate acute lung injury risk gene
22072677 The results of this study finding suggested that a model by which the self-assembly of SYD-2/Liprin-alpha proteins mediated by the coiled-coil LH1 domain is one of the key steps to the accumulation of presynaptic components at nascent synaptic junctions
21157931 These results suggest that an increased expression of Liprin-alpha1 in the brain may be associated with human Intractable epilepsy .
20096687 Data show that increased levels of liprin-alpha1 affected the localization of inactive, low-affinity integrins, while increasing the average size of beta1 integrin-positive focal adhesions.
19787783 Amplification of both PPFIA1 and CCND1 were significantly associated with high-grade breast cancer phenotype but were unrelated to tumor stage or nodal stage
19690048 Liprin is an essential regulator of cell motility that contributes to the effectiveness of cell-edge protrusion.
18196592 Amplification and overexpression of PPFIA1, a putative 11q13 invasion suppressor gene, is associated with head and neck squamous cell carcinoma
17419996 regulated degradation of liprinalpha1 is important for proper LAR receptor distribution, and could provide a mechanism for localized control of dendrite and synapse morphogenesis by activity and CaMKII.
16313174 liprin binds to ATP-agarose, challenged by free ATP, not by free GTP. Liprin LH region mutations inhibit liprin phosphorylation stabilized association of liprin with ATP-agarose. Suggests that liprin autophosphorylation regulates its association with LAR.
12923177 the interaction between ERC2 and liprin-alpha may be involved in the presynaptic localization of liprin-alpha and the molecular organization of presynaptic active zones
