General annotation (Comments)

Function

Component of the COPII coat, that covers ER-derived vesicles involved in transport from the endoplasmic reticulum to the Golgi apparatus. COPII acts in the cytoplasm to promote the transport of secretory, plasma membrane, and vacuolar proteins from the endoplasmic reticulum to the Golgi complex.

Subunit structure

COPII is composed of at least five proteins: the Sec23/24 complex, the Sec13/31 complex and Sar1. SEC24A is capable of forming heterodimers with SEC24B and SEC24C. Interacts with TMED2. Ref.4

Subcellular location

Cytoplasm By similarity. Cytoplasm › perinuclear region By similarity. Endoplasmic reticulum membrane By similarity. Golgi apparatus membrane By similarity.

Tissue specificity

Expressed in fibroblasts, hepatocytes, and lymphocytes.

Sequence similarities

Belongs to the SEC23/SEC24 family. SEC24 subfamily.

Sequence caution

The sequence CAA10334.1 differs from that shown. Reason: Frameshift at position 68.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: O95486-1)

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: O95486-2)

The sequence of this isoform differs from the canonical sequence as follows:
     594-613: LVQDLLKTLPQMFTKTLETQ → SVIGVSSEETLITCLEIAMR
     614-1093: Missing.
Note: No experimental confirmation available.
