Function
Plus-end tracking protein (+TIP) that 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. Also acts as a regulator of minus-end microtubule organization: interacts with the complex formed by AKAP9 and PDE4DIP, leading to recruit CAMSAP2 to the Golgi apparatus, thereby tethering non-centrosomal minus-end microtubules to the Golgi, an important step for polarized cell movement. Promotes elongation of CAMSAP2-decorated microtubule stretches on the minus-end of microtubules. Acts as a regulator of autophagosome transport via interaction with CAMSAP2 (By similarity). May play a role in cell migration (PubMed:15311282). UniProt

Subunit Structure
Homodimer (By similarity). Heterodimer with MAPRE3 (By similarity). Interacts with APC (via C-terminal domain), DCTN1, DIAPH1, DIAPH2 (PubMed:15311282). Interacts with DCTN2, TERF1 and dynein intermediate chain (By similarity). Interacts with CLASP2, DST, KIF2C and STIM1; probably required for their targeting to the growing microtubule plus ends (By similarity). Interacts with MTUS2; interaction is direct and probably targets MTUS2 to microtubules (By similarity). Interacts with APC2 (By similarity). Interacts with CLASP1 (By similarity). Interacts (via C-terminus) with CLIP1 (By similarity). Interacts with SLAIN2 and SLAIN1 (PubMed:21646404). According to PubMed:19553473, MAPRE1 does not interact with CDK5RAP2 (PubMed:19553473). 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 (By similarity). Interacts with NCKAP5L (By similarity). Interacts with AKAP9 (By similarity). Interacts with PDE4DIP (By similarity). Interacts with CAMSAP2. UniProt
Domain
Composed of two functionally independent domains. The N-terminal domain forms a hydrophobic cleft involved in microtubule binding and the C-terminal is involved in the formation of mutually exclusive complexes with APC and DCTN1. UniProt

Data origin/color codes
The vertical color bar on the left side indicates data provenance.
Data in green originates from UniProtKB  
Variation data (sourced from UniProt) shows non-genetic variation from the ExPASy   and dbSNP   websites.
Data in yellow originates from Pfam  , by interacting with the HMMER3 web site  
Data in purple originates from Phosphosite  .
Data in orange originates from the SCOP   (version 1.75) and SCOPe   (version 2.04) classifications.
Data in grey has been calculated using BioJava  . Protein disorder predictions are based on JRONN (Troshin, P. and Barton, G. J. unpublished), a Java implementation of RONN  
  • Red: potentially disorderd region
  • Blue: probably ordered region.
Hydropathy has been calculated using a sliding window of 15 residues and summing up scores from standard hydrophobicity tables.
  • Red: hydrophobic
  • Blue: hydrophilic.
Data in lilac represent the genomic exon structure projected onto the UniProt sequence.
Data in blue originates from PDB

Sequence Mismatches It is now possible to see information about expression tags, cloning artifacts, and many other details related to sequence mismatches.
Icons represent a number of different sequence modifications that can be observed in PDB files. For example the 'T' icon T represents expression tags that have been added to the sequence. The 'E' icon E represents an engineered mutation. However, besides these two, there are many other icons. For more information about the meaning and exact position of a sequence modification, move the cursor over the icon.
