Protein attributes

Sequence length	306 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Involved in EGFR signaling. Ref.3
Subcellular location	Cytoplasm. Note: Associated with microtubules of the cytoskeleton and mitotic apparatus By similarity.
Tissue specificity	Isoform 1 and isoform 2 are co-expressed in placenta, liver, lung, kidney and pancreas. Only isoform 1 is detected in skeletal muscle, brain and heart. Ref.1
Post-translational modification	Phosphorylated on tyrosine residues. Ref.3 Ref.4 Ref.5 Ref.7 Ref.9
Involvement in disease	Defects in CCDC50 are the cause of deafness autosomal dominant type 44 (DFNA44) [MIM:607453]. A form of non-syndromic hearing loss. It is initially moderate and affects mainly low to mid frequencies. Later, it progresses to involve all the frequencies and leads to a profound hearing loss by the 6th decade. The onset of the hearing loss occurs in the first decade of life. Ref.6
Miscellaneous	Found in a critical region of hereditary spastic paraplegia (HSP) SPG14 locus. No causative CCDC50 mutations were found in HSP families.
