17. Suppression of IRSp53 expression inhibited IGF-I-induced membrane targeting and local accumulation of WAVE2 at the leading edge of cells. PMID: 20621182
18. Cdc42 regulates the activity of IRSp53 by regulating the IRSp53-WIRE interaction as well as localization of the complex to plasma membrane to generate filopodia. PMID: 20678498
19. IRSp53, through its interaction with Eps8, not only affects cell migration but also dictates cellular growth in cancer cells. PMID: 20418908
20. IRSp53 and spinophilin regulate localized Rac activation by T-lymphocyte invasion and metastasis protein 1 PMID: 20360004
21. this work does not conform to current views that the inverse-BAR domain or Cdc42 controls IRSp53 localization but provides an alternative model of how IRSp53 is recruited (and released) to carry out its functions at lamellipodia and filopodia. PMID: 19933840
22. LIN7B is a partner of IRSp53 anchoring the actin-based membrane cytoskeleton at cell-cell contacts. PMID: 14596909
23. IRSp53, when activated by small GTPases, participates in F-actin reorganization not only in an SH3-dependent manner but also in a manner dependent on the activity of the IRSp53/MIM homology domain PMID: 14752106
24. IRSp53 comprises a central SH3 domain, which binds to proline-rich regions of a wide range of actin regulators, and a conserved N-terminal IRSp53/MIM homology domain that harbours F-actin-bundling activity. Presents crystal structure of this novel domain PMID: 15635447
25. These results suggest that PSD-95 interaction is an important determinant of synaptic IRSp53 localization and that the SH3 domain of IRSp53 links activated Rac1/Cdc42 to downstream effectors for the regulation of spine morphogenesis. PMID: 15673667
26. The mechanism of membrane deforamtion induced by the IRSp53 RCB domain is reported. PMID: 17003044
27. These results support a model whereby the synergic bundling activity of the IRSp53-Eps8 complex, regulated by Cdc42, contributes to the generation of actin bundles, thus promoting filopodial protrusions. PMID: 17115031
28. Together, these data reveal that interplay between actin dynamics and a novel membrane-deformation activity promotes cell motility and morphogenesis. PMID: 17371834
29. tyrosine 310 as a primary site of tyrosine phosphorylation in response to insulin signalling and we have shown that although IRSp53 is tyrosine phosphorylated in response to epidermal growth factor receptor signalling, tyrosine 310 is not crucial. PMID: 18417251

31. Both spatial learning and novel object recognition are impaired in transgenic mice deficient of IRSp53 expression. PMID: 19193906
32. The authors show that IRSp53 family members, key regulators of membrane and actin dynamics, directly interact with both Tir and EspF(U).[Tir & EspFU] PMID: 19286134
33. SPIN90 and IRSp53 positively cooperated to mediate Rac activation, and co-expression of SPIN90 and IRSp53 in COS-7 cells led to the complex formation of SPIN90-IRSp53 in the leading edge of cells PMID: 19460367
