This gene encodes a member of the IMD (IRSp53/MIM homology domain) family. Members of this family can be subdivided in two groups, the IRSp53-like and MIM-like, based on the presence or absence of the SH3 (Src homology 3) domain. The protein encoded by this gene contains a conserved IMD, also known as F-actin bundling domain, at the N-terminus, and a canonical SH3 domain near the C-terminus, so it belongs to the IRSp53-like group. This protein is the substrate for insulin receptor tyrosine kinase and binds to the small GTPase Rac. It is involved in signal transduction pathways that link deformation of the plasma membrane and remodeling of the actin cytoskeleton. It also promotes actin assembly and membrane protrusions when overexpressed in mammalian cells, and is essential to the formation of a potent actin assembly complex during EHEC (Enterohemorrhagic Escherichia coli) pedestal formation.

Forensic Context
A study in mice demonstrated that the BAIAP2L1 was the most downregulated gene (0.260-fold reduction) in lung tissue following hypothermia-induced death, identifying it as a candidate forensic biomarker for hypothermia [Takamiya et al. DOI:10.1016/J.Legalmed.2020.101789]. In a separate investigation using a perinatal glyphosate exposure mouse model, the BAIAP2L1 was identified as a top upregulated mRNA (22.50-fold increase) in hippocampal tissue, suggesting its potential as a biomarker for glyphosate-induced neurotoxicity [Xingli Fan et al. DOI:10.1002/jdn.10102].
