Summary: Enables cytoskeletal protein binding activity; protein kinase A binding activity; and small GTPase binding activity. Predicted to be involved in positive regulation of insulin secretion. Predicted to act upstream of or within vesicle transport along actin filament. Located in several cellular components, including actin cytoskeleton; melanosome; and photoreceptor outer segment. Part of exocyst. Is expressed in several structures, including gut; heart; lung; male reproductive gland or organ; and nervous system. Orthologous to human MYRIP (myosin VIIA and Rab interacting protein). [provided by Alliance of Genome Resources, Dec 2024]

Here, the authors show that exophilin-8 accumulates granules in the cortical F-actin network not by direct interaction with myosin-Va, but by indirect interaction with a specific form of myosin-VIIa through its previously unknown binding partner, RIM-BP2.
Title: Exophilin-8 assembles secretory granules for exocytosis in the actin cortex via interaction with RIM-BP2 and myosin-VIIa.
Exophilin8 transiently clusters insulin granules at the actin-rich cell cortex prior to exocytosis
Title: Exophilin8 transiently clusters insulin granules at the actin-rich cell cortex prior to exocytosis.
Myrip is a versatile Rab27a-associated myosin-activating protein that mediates cellular activation of MyoVa and MyoVIIa via non-overlapping domains.
Title: Myrip uses distinct domains in the cellular activation of myosin VA and myosin VIIA in melanosome transport.
Results suggest that the Rab27a-Myrip-MyoVIIa complex regulates tethering of melanosomes onto actin filaments, a process that ensures melanosome movement towards the cell periphery.
Title: The ternary Rab27a-Myrip-Myosin VIIa complex regulates melanosome motility in the retinal pigment epithelium.
indicate that MyRIP functions as a scaffolding protein that links protein kinase A to components of the exocytosis machinery
Title: MyRIP anchors protein kinase A to the exocyst complex.
The present results provide evidence from live retinal pigment epithelium cells that the RAB27A-MYRIP-MYO7A complex functions in melanosome motility.

Synaptotagmin-like protein homologue lacking C2 domains-c) is a novel linker protein that interacts with Rab27, myosin Va/VIIa, and actin
Title: Slac2-c (synaptotagmin-like protein homologue lacking C2 domains-c), a novel linker protein that interacts with Rab27, myosin Va/VIIa, and actin.
Slac2-c acts as a functional myosin VIIa receptor and the Rab27A.Slac2-c x myosin VIIa tripartite protein complex regulates the transport of retinal melanosomes in pigment epithelium cells
Title: Functional analysis of Slac2-c/MyRIP as a linker protein between melanosomes and myosin VIIa.
Slac2-c/MyRIP contains an N-terminal Slp homology domain (SHD) and functions as a linker protein that interacts with myosin Rab27A/B, VIIa/Va, and actin.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
