Annotation description:Ablim1 (Actin-binding LIM protein 1) was identified as a PSD95 (DLG4, here the bait protein) interaction partner through tandem affinity purification (TAP) proteomics (Fig. 3, Table 1). This was validated by western blot; pulldown of endogenous Ablim1 using an antibody yields PSD95.

Our results suggest that abLIM1 functions as an LLPS-dependent actin nucleator and cross-linker and provide insights into how LLPS-induced condensates could self-construct intracellular architectures of high connectivity and plasticity." @ PMID:35858327

Ablim1 is highly enriched in PSD biochemical fractions as compared to various other synaptic fractions @ PMID:28935861
