General annotation (Comments)

Function

Receptor for members of the ephrin-A family. Binds to ephrin-A1, -A2, -A3, -A4 and -A5.

Catalytic activity

ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.

Subunit structure

Interacts with PRKCABP and GRIP1 By similarity.

Subcellular location

Membrane; Single-pass type I membrane protein.

Tissue specificity

Widely expressed.

Sequence similarities

Belongs to the protein kinase superfamily. Tyr protein kinase family. Ephrin receptor subfamily.

Contains 2 fibronectin type-III domains.

Contains 1 protein kinase domain.

Contains 1 SAM (sterile alpha motif) domain.

Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q15375-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: Q15375-2)

The sequence of this isoform differs from the canonical sequence as follows:
     540-544: Missing.
Note: No experimental confirmation available. May be due to a competing donor splice site.
Isoform 3 (identifier: Q15375-3)

The sequence of this isoform differs from the canonical sequence as follows:
     278-279: PC → RK
     280-998: Missing.
Note: No experimental confirmation available.
