Function

[DYL1_HUMAN] Acts as one of several non-catalytic accessory components of the cytoplasmic dynein 1 complex that are thought to be involved in linking dynein to cargos and to adapter proteins that regulate dynein function. Cytoplasmic dynein 1 acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules. May play a role in changing or maintaining the spatial distribution of cytoskeletal structures.^[1] ^[2] ^[3] ^[4] Binds and inhibits the catalytic activity of neuronal nitric oxide synthase.^[5] ^[6] ^[7] ^[8] Promotes transactivation functions of ESR1 and plays a role in the nuclear localization of ESR1.^[9] ^[10] ^[11] ^[12] Regulates apoptotic activities of BCL2L11 by sequestering it to microtubules. Upon apoptotic stimuli the BCL2L11-DYNLL1 complex dissociates from cytoplasmic dynein and translocates to mitochondria and sequesters BCL2 thus neutralizing its antiapoptotic activity.^[13] ^[14] ^[15] ^[16]

Publication Abstract from PubMed

The NIMA-family protein kinases Nek9/Nercc1, Nek6 and Nek7 constitute a signaling module activated in early mitosis involved in the control of spindle organization. DYNLL/LC8 (dynein light chain 8) was originally described as a component of the dynein complex, but the recent discovery of multiple interaction partners for LC8 has suggested that it has a general role as a dimerization hub that organizes different protein partners. Recent experiments suggested that LC8 binding to Nek9 was regulated by Nek9 autophosphorylation on Ser944, a residue immediately located N-terminal to the LC8 conserved (K/R)xTQT binding motif, and that this was crucial for the control of signal transduction through the Nek/Nek6/7 module. In the present work we present two crystal structures of LC8 with a peptide corresponding to the Nek9 binding region with and without a phosphorylation on Ser944. Structural analysis of LC8 with both Nek9 peptides, together with different biophysical experiments, explains the observed diminished binding affinity of Nek9 to LC8 upon phosphorylation on Ser944 within the Nek9 sequence, thus shedding light into a novel phosphorylation regulatory mechanism that interferes with LC8 protein-protein complex formation.
