Protein attributes

Sequence length	765 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

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. Interacts with SEC23IP. Interacts with HTR4 By similarity. Interacts with SEC16A.
Subcellular location	Smooth endoplasmic reticulum membrane; Peripheral membrane protein. Golgi apparatus membrane; Peripheral membrane protein Potential. Note: In the ribosome-free transitional face of the ER and associated vesicles.
Involvement in disease	Defects in SEC23A are the cause of craniolenticulosutural dysplasia (CLSD) [MIM:607812]; also known as cranio-lenticulo-sutural dysplasia. CLSD is an autosomal recessive syndrome characterized by late-closing fontanels, sutural cataracts, facial dysmorphisms and skeletal defects. Ref.9
Sequence similarities	Belongs to the SEC23/SEC24 family. SEC23 subfamily.
