    Summary
    Involved in several processes, including anterograde synaptic vesicle transport; neuron development; and synapse organization. Located in focal adhesion and presynaptic active zone. Part of protein-containing complex. Is expressed in several structures, including embryonic/larval central nervous system; neuromuscular junction; presumptive embryonic/larval nervous system; spermatozoon; and synapse. Orthologous to several human genes including PPFIA1 (PTPRF interacting protein alpha 1) and PPFIA2 (PTPRF interacting protein alpha 2). [provided by Alliance of Genome Resources, Apr 2022]

    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    1. Our live data support a "serial synapse formation" model, where at any time point only 1-2 "synaptogenic" filopodia suppress the synaptic competence of other filopodia through competition for synaptic seeding factors. Loss of the synaptic seeding factors Syd-1 and Liprin-alpha leads to a loss of this suppression, filopodial destabilization, and reduced synapse formation.

    2. Loss of function of liprin-alpha causes accumulation of ectopic materials in synapses of distal axons.
      Title: Drosophila Syd-1, liprin-α, and protein phosphatase 2A B' subunit Wrd function in a linear pathway to prevent ectopic accumulation of synaptic materials in distal axons.
    3. Context-specific interactions among three liprins (liprin-alpha, -beta, and -gamma) suggest that the R7 photoreceptor and neuromuscular junction synapses differ in their assembly mechanisms.
      Title: Three Drosophila liprins interact to control synapse formation.
    4. Data demonstrate that N-cadherin, DLAR, and Liprin-alpha function in a complex to regulate adhesive interactions between pre- and post-synaptic cells and provide a novel mechanism for controlling the activity of Liprin-alpha in the developing growth cone.
      Title: Complex interactions amongst N-cadherin, DLAR, and Liprin-alpha regulate Drosophila photoreceptor axon targeting.
    5. Results suggest that Liprin-alpha does not simply act by regulating receptor tyrosine phosphatase LAR localization but also has LAR-independent functions.
