Protein

Microtubule-associated protein RP/EB family member 1

Gene

Mapre1

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Binds to the plus end of microtubules and regulates the dynamics of the microtubule cytoskeleton. Promotes cytoplasmic microtubule nucleation and elongation. May be involved in spindle function by stabilizing microtubules and anchoring them at centrosomes (By similarity). May play a role in cell migration.By similarity1 Publication

Interactioni

Subunit structurei

Homodimer. Heterodimer with MAPRE3. Interacts with DCTN1, DCTN2, DIAPH1, DIAPH2, TERF1 and dynein intermediate chain. Interacts with APC (via C-terminal domain), CLASP2, DST, KIF2C and STIM1; probably required for their targeting to the growing microtubule plus ends. Interacts with MTUS2; interaction is direct and probably targets MTUS2 to microtubules. Interacts with APC2. Interacts with CLASP1. Interacts (via C-terminus) with CLIP1. Interacts with SLAIN2 (PubMed:21646404). According to PubMed:19553473, MAPRE1 does not interact with CDK5RAP2. Interacts with MACF1 (PubMed:18854161). Interacts with KIF18B; this interaction is required for efficient accumulation of KIF18B at microtubule plus ends (By similarity). Interacts with MISP (By similarity). Interacts with RABL2/RABL2A; binds preferentially to GTP-bound RABL2 (PubMed:23055941). Interacts with KCNAB2 (PubMed:21357749). Interacts with KNSTRN. Interacts with NCKAP5L (By similarity).By similarity6 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
