Rabbit Anti-MICAL3 antibody
MICAL3 is a 976 amino acid protein that localizes to both the cytoplasm and the cytoskeleton and contains one LIM zinc-binding domain and one calponin-homology domain. Expressed ubiquitously, MICAL3 uses FAD as a cofactor to interact with Rab 1B and, via this interaction, is thought to play a role in spermatid development. MICAL3 exists as two alternatively spliced isoforms that are encoded by a gene which maps to human chromosome 22. Chromosome 22 houses over 500 genes, some of which are involved in Phelan-McDermid syndrome, schizophrenia and Neurofibromatosis type 2.
Function:
Monooxygenase that promotes depolymerization of F-actin by mediating oxidation of specific methionine residues on actin. Acts by modifying actin subunits through the addition of oxygen to form methionine-sulfoxide, leading to promote actin filament severing and prevent repolymerization. Involved in exocytic vesicles tethering and fusion: the monooxygenase activity is required for this process.
Subunit:
Interacts with RAB1B. Interacts with ERC1 and RAB8A.
Subcellular Location:
Cytoplasm.
Tissue Specificity:
Ubiquitous.
Similarity:
Belongs to the Mical family.
Contains 1 CH (calponin-homology) domain.
Contains 1 LIM zinc-binding domain.
