MTMR9 is a catalytically inactive pseudophosphatase that lacks the catalytic cysteine in the CX5R motif

MTMR9 forms heterodimeric complexes with MTMR6, MTMR7, and MTMR8, modulating their localization and substrate specificity

MTMR9 recruits MTMR6 and MTMR8 to the intermediate compartment and Golgi apparatus, sustaining Golgi integrity and ER-to-Golgi transport

No direct experimental data exist for A0A8B6GS20 in Mytilus galloprovincialis; all functional annotations are inferred from orthologous proteins in model organisms
